Title
ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port()
The if statement:
if (port >= DSAF_GE_NUM)
return;
limits the value of port less than DSAF_GE_NUM (i.e., 8).
However, if the value of port is 6 or 7, an array overflow could occur:
port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off;
because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6).
To fix this possible array overflow, we first check port and if it is
greater than or equal to DSAF_MAX_PORT_NUM, the function returns.
Severity ?
9.8 (Critical)
CWE
- CWE-129 - Improper Validation of Array Index

Title
i2c: core: Run atomic i2c xfer when !preemptible
Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: core: Run atomic i2c xfer when !preemptible
Since bae1d3a05a8b, i2c transfers are non-atomic if preemption is
disabled. However, non-atomic i2c transfers require preemption (e.g. in
wait_for_completion() while waiting for the DMA).
panic() calls preempt_disable_notrace() before calling
emergency_restart(). Therefore, if an i2c device is used for the
restart, the xfer should be atomic. This avoids warnings like:
[ 12.667612] WARNING: CPU: 1 PID: 1 at kernel/rcu/tree_plugin.h:318 rcu_note_context_switch+0x33c/0x6b0
[ 12.676926] Voluntary context switch within RCU read-side critical section!
...
[ 12.742376] schedule_timeout from wait_for_completion_timeout+0x90/0x114
[ 12.749179] wait_for_completion_timeout from tegra_i2c_wait_completion+0x40/0x70
...
[ 12.994527] atomic_notifier_call_chain from machine_restart+0x34/0x58
[ 13.001050] machine_restart from panic+0x2a8/0x32c
Use !preemptible() instead, which is basically the same check as
pre-v5.2.

Title
of: Fix double free in of_parse_phandle_with_args_map
Summary
In the Linux kernel, the following vulnerability has been resolved:
of: Fix double free in of_parse_phandle_with_args_map
In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.
Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".
Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.
Severity ?
No CVSS data available.

Title
wifi: ath11k: fix gtk offload status event locking
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix gtk offload status event locking
The ath11k active pdevs are protected by RCU but the gtk offload status
event handling code calling ath11k_mac_get_arvif_by_vdev_id() was not
marked as a read-side critical section.
Mark the code in question as an RCU read-side critical section to avoid
any potential use-after-free issues.
Compile tested only.
Severity ?
No CVSS data available.

Title
tracing: Restructure trace_clock_global() to never block
Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Restructure trace_clock_global() to never block
It was reported that a fix to the ring buffer recursion detection would
cause a hung machine when performing suspend / resume testing. The
following backtrace was extracted from debugging that case:
Call Trace:
trace_clock_global+0x91/0xa0
__rb_reserve_next+0x237/0x460
ring_buffer_lock_reserve+0x12a/0x3f0

? ring_buffer_lock_reserve+0x12a/0x3f0
? trace_event_buffer_lock_reserve+0x3c/0x120
? trace_event_buffer_reserve+0x6b/0xc0

? platform_get_irq_byname_optional+0x90/0x90
? trace_device_pm_callback_start+0x82/0xd0
? dpm_run_callback+0x49/0xc0
With the following RIP:
RIP: 0010:native_queued_spin_lock_slowpath+0x69/0x200
Since the fix to the recursion detection would allow a single recursion to
happen while tracing, this lead to the trace_clock_global() taking a spin
lock and then trying to take it again:
ring_buffer_lock_reserve() {
trace_clock_global() {
arch_spin_lock() {
queued_spin_lock_slowpath() {
/* lock taken */
(something else gets traced by function graph tracer)
ring_buffer_lock_reserve() {
trace_clock_global() {
arch_spin_lock() {
queued_spin_lock_slowpath() {
/* DEAD LOCK! */
Tracing should *never* block, as it can lead to strange lockups like the
above.
Restructure the trace_clock_global() code to instead of simply taking a
lock to update the recorded "prev_time" simply use it, as two events
happening on two different CPUs that calls this at the same time, really
doesn't matter which one goes first. Use a trylock to grab the lock for
updating the prev_time, and if it fails, simply try again the next time.
If it failed to be taken, that means something else is already updating
it.

Title
SUNRPC: Fix RPC client cleaned up the freed pipefs dentries
Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Fix RPC client cleaned up the freed pipefs dentries
RPC client pipefs dentries cleanup is in separated rpc_remove_pipedir()
workqueue,which takes care about pipefs superblock locking.
In some special scenarios, when kernel frees the pipefs sb of the
current client and immediately alloctes a new pipefs sb,
rpc_remove_pipedir function would misjudge the existence of pipefs
sb which is not the one it used to hold. As a result,
the rpc_remove_pipedir would clean the released freed pipefs dentries.
To fix this issue, rpc_remove_pipedir should check whether the
current pipefs sb is consistent with the original pipefs sb.
This error can be catched by KASAN:

Title
wifi: ath11k: decrease MHI channel buffer length to 8KB
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: decrease MHI channel buffer length to 8KB
Currently buf_len field of ath11k_mhi_config_qca6390 is assigned
with 0, making MHI use a default size, 64KB, to allocate channel
buffers. This is likely to fail in some scenarios where system
memory is highly fragmented and memory compaction or reclaim is
not allowed.
There is a fail report which is caused by it:
kworker/u32:45: page allocation failure: order:4, mode:0x40c00(GFP_NOIO|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0

Actually those buffers are used only by QMI target -> host communication.
And for WCN6855 and QCA6390, the largest packet size for that is less
than 6KB. So change buf_len field to 8KB, which results in order 1
allocation if page size is 4KB. In this way, we can at least save some
memory, and as well as decrease the possibility of allocation failure
in those scenarios.

Title
wifi: brcmfmac: pcie: handle randbuf allocation failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: pcie: handle randbuf allocation failure
The kzalloc() in brcmf_pcie_download_fw_nvram() will return null
if the physical memory has run out. As a result, if we use
get_random_bytes() to generate random bytes in the randbuf, the
null pointer dereference bug will happen.
In order to prevent allocation failure, this patch adds a separate
function using buffer on kernel stack to generate random bytes in
the randbuf, which could prevent the kernel stack from overflow.
Severity ?
No CVSS data available.

Title
ext4: fix corruption during on-line resize
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix corruption during on-line resize
We observed a corruption during on-line resize of a file system that is
larger than 16 TiB with 4k block size. With having more then 2^32 blocks
resize_inode is turned off by default by mke2fs. The issue can be
reproduced on a smaller file system for convenience by explicitly
turning off resize_inode. An on-line resize across an 8 GiB boundary (the
size of a meta block group in this setup) then leads to a corruption:
dev=/dev/<some_dev> # should be >= 16 GiB
mkdir -p /corruption
/sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15))
mount -t ext4 $dev /corruption
dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15))
sha1sum /corruption/test
# 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test
/sbin/resize2fs $dev $((2*2**21))
# drop page cache to force reload the block from disk
echo 1 > /proc/sys/vm/drop_caches
sha1sum /corruption/test
# 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test
2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per
block group and 2^6 are the number of block groups that make a meta
block group.
The last checksum might be different depending on how the file is laid
out across the physical blocks. The actual corruption occurs at physical
block 63*2^15 = 2064384 which would be the location of the backup of the
meta block group's block descriptor. During the on-line resize the file
system will be converted to meta_bg starting at s_first_meta_bg which is
2 in the example - meaning all block groups after 16 GiB. However, in
ext4_flex_group_add we might add block groups that are not part of the
first meta block group yet. In the reproducer we achieved this by
substracting the size of a whole block group from the point where the
meta block group would start. This must be considered when updating the
backup block group descriptors to follow the non-meta_bg layout. The fix
is to add a test whether the group to add is already part of the meta
block group or not.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix corruption during on-line resize\n\nWe observed a corruption during on-line resize of a file system that is\nlarger than 16 TiB with 4k block size. With having more then 2^32 blocks\nresize_inode is turned off by default by mke2fs. The issue can be\nreproduced on a smaller file system for convenience by explicitly\nturning off resize_inode. An on-line resize across an 8 GiB boundary (the\nsize of a meta block group in this setup) then leads to a corruption:\n\n dev=/dev/\u003csome_dev\u003e # should be \u003e= 16 GiB\n mkdir -p /corruption\n /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15))\n mount -t ext4 $dev /corruption\n\n dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15))\n sha1sum /corruption/test\n # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test\n\n /sbin/resize2fs $dev $((2*2**21))\n # drop page cache to force reload the block from disk\n echo 1 \u003e /proc/sys/vm/drop_caches\n\n sha1sum /corruption/test\n # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test\n\n2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per\nblock group and 2^6 are the number of block groups that make a meta\nblock group.\n\nThe last checksum might be different depending on how the file is laid\nout across the physical blocks. The actual corruption occurs at physical\nblock 63*2^15 = 2064384 which would be the location of the backup of the\nmeta block group\u0027s block descriptor. During the on-line resize the file\nsystem will be converted to meta_bg starting at s_first_meta_bg which is\n2 in the example - meaning all block groups after 16 GiB. However, in\next4_flex_group_add we might add block groups that are not part of the\nfirst meta block group yet. In the reproducer we achieved this by\nsubstracting the size of a whole block group from the point where the\nmeta block group would start. This must be considered when updating the\nbackup block group descriptors to follow the non-meta_bg layout. The fix\nis to add a test whether the group to add is already part of the meta\nblock group or not."

Title
platform/x86: wmi: Fix opening of char device
Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: wmi: Fix opening of char device
Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via
file private data"), the miscdevice stores a pointer to itself inside
filp->private_data, which means that private_data will not be NULL when
wmi_char_open() is called. This might cause memory corruption should
wmi_char_open() be unable to find its driver, something which can
happen when the associated WMI device is deleted in wmi_free_devices().
Fix the problem by using the miscdevice pointer to retrieve the WMI
device data associated with a char device using container_of(). This
also avoids wmi_char_open() picking a wrong WMI device bound to a
driver with the same name as the original driver.
Severity ?
No CVSS data available.

scsi: qla2xxx: Fix off by one in qla_edif_app_getstats()
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix off by one in qla_edif_app_getstats()
The app_reply->elem[] array is allocated earlier in this function and it
has app_req.num_ports elements. Thus this > comparison needs to be >= to
prevent memory corruption.

Title
mmc: sdio: fix possible resource leaks in some error paths
Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdio: fix possible resource leaks in some error paths
If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can
not release the resources, because the sdio function is not presented
in these two cases, it won't call of_node_put() or put_device().
To fix these leaks, make sdio_func_present() only control whether
device_del() needs to be called or not, then always call of_node_put()
and put_device().
In error case in sdio_init_func(), the reference of 'card->dev' is
not get, to avoid redundant put in sdio_free_func_cis(), move the
get_device() to sdio_alloc_func() and put_device() to sdio_release_func(),
it can keep the get/put function be balanced.
Without this patch, while doing fault inject test, it can get the
following leak reports, after this fix, the leak is gone.

Title
scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()
The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an
unsuccessful status. In such cases, the elsiocb is not issued, the
completion is not called, and thus the elsiocb resource is leaked.
Check return value after calling lpfc_sli4_resume_rpi() and conditionally
release the elsiocb resource.
Severity ?
No CVSS data available.

Title
pstore/ram: Fix crash when setting number of cpus to an odd number
Summary
In the Linux kernel, the following vulnerability has been resolved:
pstore/ram: Fix crash when setting number of cpus to an odd number
When the number of cpu cores is adjusted to 7 or other odd numbers,
the zone size will become an odd number.
The address of the zone will become:
addr of zone0 = BASE
addr of zone1 = BASE + zone_size
addr of zone2 = BASE + zone_size*2
...
The address of zone1/3/5/7 will be mapped to non-alignment va.
Eventually crashes will occur when accessing these va.
So, use ALIGN_DOWN() to make sure the zone size is even
to avoid this bug.
Severity ?

Title
media: gspca: cpia1: shift-out-of-bounds in set_flicker
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: gspca: cpia1: shift-out-of-bounds in set_flicker
Syzkaller reported the following issue:
UBSAN: shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27
shift exponent 245 is too large for 32-bit type 'int'
When the value of the variable "sd->params.exposure.gain" exceeds the
number of bits in an integer, a shift-out-of-bounds error is reported. It
is triggered because the variable "currentexp" cannot be left-shifted by
more than the number of bits in an integer. In order to avoid invalid
range during left-shift, the conditional expression is added.
Severity ?

Title
wifi: mac80211: don't return unset power in ieee80211_get_tx_power()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't return unset power in ieee80211_get_tx_power()
We can get a UBSAN warning if ieee80211_get_tx_power() returns the
INT_MIN value mac80211 internally uses for "unset power level".
UBSAN: signed-integer-overflow in net/wireless/nl80211.c:3816:5
-2147483648 * 100 cannot be represented in type 'int'
CPU: 0 PID: 20433 Comm: insmod Tainted: G WC OE

In this case, simply return an error instead, to indicate
that no data is available.

Title
tcp: add sanity checks to rx zerocopy
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: add sanity checks to rx zerocopy
TCP rx zerocopy intent is to map pages initially allocated
from NIC drivers, not pages owned by a fs.
This patch adds to can_map_frag() these additional checks:
- Page must not be a compound one.
- page->mapping must be NULL.
This fixes the panic reported by ZhangPeng.
syzbot was able to loopback packets built with sendfile(),
mapping pages owned by an ext4 file to TCP rx zerocopy.
r3 = socket$inet_tcp(0x2, 0x1, 0x0)
mmap(&(0x7f0000ff9000/0x4000)=nil, 0x4000, 0x0, 0x12, r3, 0x0)
r4 = socket$inet_tcp(0x2, 0x1, 0x0)

Title
net/sched: act_skbmod: prevent kernel-infoleak
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_skbmod: prevent kernel-infoleak
syzbot found that tcf_skbmod_dump() was copying four bytes
from kernel stack to user space [1].
The issue here is that 'struct tc_skbmod' has a four bytes hole.
We need to clear the structure before filling fields.

Title
NFSv4.2: fix nfs4_listxattr kernel BUG at mm/usercopy.c:102
Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4.2: fix nfs4_listxattr kernel BUG at mm/usercopy.c:102
A call to listxattr() with a buffer size = 0 returns the actual
size of the buffer needed for a subsequent call. When size > 0,
nfs4_listxattr() does not return an error because either
generic_listxattr() or nfs4_listxattr_nfs4_label() consumes
exactly all the bytes then size is 0 when calling
nfs4_listxattr_nfs4_user() which then triggers the following
kernel BUG:

[ 99.418994] Code: aa0003e3 d000a3e0 91310000 97f49bdb (d4210000)
Issue is reproduced when generic_listxattr() returns 'system.nfs4_acl',
thus calling lisxattr() with size = 16 will trigger the bug.
Add check on nfs4_listxattr() to return ERANGE error when it is
called with size > 0 and the return value is greater than size.

Title
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
Anderson Nascimento reported a use-after-free splat in tcp_twsk_unique()
with nice analysis.
Since commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for
timewait hashdance"), inet_twsk_hashdance() sets TIME-WAIT socket's
sk_refcnt after putting it into ehash and releasing the bucket lock.
Thus, there is a small race window where other threads could try to
reuse the port during connect() and call sock_hold() in tcp_twsk_unique()
for the TIME-WAIT socket with zero refcnt.
If that happens, the refcnt taken by tcp_twsk_unique() is overwritten
and sock_put() will cause underflow, triggering a real use-after-free
somewhere else.
To avoid the use-after-free, we need to use refcount_inc_not_zero() in
tcp_twsk_unique() and give up on reusing the port if it returns false.
[0]:
refcount_t: addition on 0; use-after-free.

Title
USB: core: Fix access violation during port device removal
Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix access violation during port device removal
Testing with KASAN and syzkaller revealed a bug in port.c:disable_store():
usb_hub_to_struct_hub() can return NULL if the hub that the port belongs to
is concurrently removed, but the function does not check for this
possibility before dereferencing the returned value.
It turns out that the first dereference is unnecessary, since hub->intfdev
is the parent of the port device, so it can be changed easily. Adding a
check for hub == NULL prevents further problems.
The same bug exists in the disable_show() routine, and it can be fixed the
same way.

Title
x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD
Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD
Commit 672365477ae8 ("x86/fpu: Update XFD state where required") and
commit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a
per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in
order to avoid unnecessary writes to the MSR.
On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which
wipes out any stale state. But the per CPU cached xfd value is not
reset, which brings them out of sync.
As a consequence a subsequent xfd_update_state() might fail to update
the MSR which in turn can result in XRSTOR raising a #NM in kernel
space, which crashes the kernel.
To fix this, introduce xfd_set_state() to write xfd_state together
with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

Title
mm/hugetlb: fix missing hugetlb_lock for resv uncharge
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: fix missing hugetlb_lock for resv uncharge
There is a recent report on UFFDIO_COPY over hugetlb:
https://lore.kernel.org/all/000000000000ee06de0616177560@google.com/
350: lockdep_assert_held(&hugetlb_lock);
Should be an issue in hugetlb but triggered in an userfault context, where
it goes into the unlikely path where two threads modifying the resv map
together. Mike has a fix in that path for resv uncharge but it looks like
the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd()
will update the cgroup pointer, so it requires to be called with the lock
held.
Severity ?
No CVSS data available.

Title
wifi: cfg80211: check A-MSDU format more carefully
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: check A-MSDU format more carefully
If it looks like there's another subframe in the A-MSDU
but the header isn't fully there, we can end up reading
data out of bounds, only to discard later. Make this a
bit more careful and check if the subframe header can
even be present.
Severity ?
No CVSS data available.

Title
firewire: ohci: mask bus reset interrupts between ISR and bottom half
Summary
In the Linux kernel, the following vulnerability has been resolved:
firewire: ohci: mask bus reset interrupts between ISR and bottom half
In the FireWire OHCI interrupt handler, if a bus reset interrupt has
occurred, mask bus reset interrupts until bus_reset_work has serviced and
cleared the interrupt.
Normally, we always leave bus reset interrupts masked. We infer the bus
reset from the self-ID interrupt that happens shortly thereafter. A
scenario where we unmask bus reset interrupts was introduced in 2008 in
a007bb857e0b26f5d8b73c2ff90782d9c0972620: If
OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we
will unmask bus reset interrupts so we can log them.
irq_handler logs the bus reset interrupt. However, we can't clear the bus
reset event flag in irq_handler, because we won't service the event until
later. irq_handler exits with the event flag still set. If the
corresponding interrupt is still unmasked, the first bus reset will
usually freeze the system due to irq_handler being called again each
time it exits. This freeze can be reproduced by loading firewire_ohci
with "modprobe firewire_ohci debug=-1" (to enable all debugging output).
Apparently there are also some cases where bus_reset_work will get called
soon enough to clear the event, and operation will continue normally.
This freeze was first reported a few months after a007bb85 was committed,
but until now it was never fixed. The debug level could safely be set
to -1 through sysfs after the module was loaded, but this would be
ineffectual in logging bus reset interrupts since they were only
unmasked during initialization.
irq_handler will now leave the event flag set but mask bus reset
interrupts, so irq_handler won't be called again and there will be no
freeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will
unmask the interrupt after servicing the event, so future interrupts
will be caught as desired.
As a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be
enabled through sysfs in addition to during initial module loading.
However, when enabled through sysfs, logging of bus reset interrupts will
be effective only starting with the second bus reset, after
bus_reset_work has executed.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirewire: ohci: mask bus reset interrupts between ISR and bottom half\n\nIn the FireWire OHCI interrupt handler, if a bus reset interrupt has\noccurred, mask bus reset interrupts until bus_reset_work has serviced and\ncleared the interrupt.\n\nNormally, we always leave bus reset interrupts masked. We infer the bus\nreset from the self-ID interrupt that happens shortly thereafter. A\nscenario where we unmask bus reset interrupts was introduced in 2008 in\na007bb857e0b26f5d8b73c2ff90782d9c0972620: If\nOHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we\nwill unmask bus reset interrupts so we can log them.\n\nirq_handler logs the bus reset interrupt. However, we can\u0027t clear the bus\nreset event flag in irq_handler, because we won\u0027t service the event until\nlater. irq_handler exits with the event flag still set. If the\ncorresponding interrupt is still unmasked, the first bus reset will\nusually freeze the system due to irq_handler being called again each\ntime it exits. This freeze can be reproduced by loading firewire_ohci\nwith \"modprobe firewire_ohci debug=-1\" (to enable all debugging output).\nApparently there are also some cases where bus_reset_work will get called\nsoon enough to clear the event, and operation will continue normally.\n\nThis freeze was first reported a few months after a007bb85 was committed,\nbut until now it was never fixed. The debug level could safely be set\nto -1 through sysfs after the module was loaded, but this would be\nineffectual in logging bus reset interrupts since they were only\nunmasked during initialization.\n\nirq_handler will now leave the event flag set but mask bus reset\ninterrupts, so irq_handler won\u0027t be called again and there will be no\nfreeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will\nunmask the interrupt after servicing the event, so future interrupts\nwill be caught as desired.\n\nAs a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be\nenabled through sysfs in addition to during initial module loading.\nHowever, when enabled through sysfs, logging of bus reset interrupts will\nbe effective only starting with the second bus reset, after\nbus_reset_work has executed."

Title
mlxsw: spectrum_acl_tcam: Fix incorrect list API usage
Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix incorrect list API usage
Both the function that migrates all the chunks within a region and the
function that migrates all the entries within a chunk call
list_first_entry() on the respective lists without checking that the
lists are not empty. This is incorrect usage of the API, which leads to
the following warning [1].
Fix by returning if the lists are empty as there is nothing to migrate
in this case.

Title
efivarfs: force RO when remounting if SetVariable is not supported
Summary
In the Linux kernel, the following vulnerability has been resolved:
efivarfs: force RO when remounting if SetVariable is not supported
If SetVariable at runtime is not supported by the firmware we never assign
a callback for that function. At the same time mount the efivarfs as
RO so no one can call that. However, we never check the permission flags
when someone remounts the filesystem as RW. As a result this leads to a
crash looking like this:
$ mount -o remount,rw /sys/firmware/efi/efivars

isdn: mISDN: Fix sleeping function called from invalid context
Summary
In the Linux kernel, the following vulnerability has been resolved:
isdn: mISDN: Fix sleeping function called from invalid context
The driver can call card->isac.release() function from an atomic
context.
Fix this by calling this function after releasing the lock.

Title
nfs: fix UAF in direct writes
Summary
In the Linux kernel, the following vulnerability has been resolved:
nfs: fix UAF in direct writes
In production we have been hitting the following warning consistently
------------[ cut here ]------------
refcount_t: underflow; use-after-free.
WARNING: CPU: 17 PID: 1800359 at lib/refcount.c:28 refcount_warn_saturate+0x9c/0xe0
Workqueue: nfsiod nfs_direct_write_schedule_work [nfs]
RIP: 0010:refcount_warn_saturate+0x9c/0xe0

? __btf_name_valid+0xa0/0xa0
ret_from_fork+0x1f/0x30
This is because we're completing the nfs_direct_request twice in a row.
The source of this is when we have our commit requests to submit, we
process them and send them off, and then in the completion path for the
commit requests we have
if (nfs_commit_end(cinfo.mds))
nfs_direct_write_complete(dreq);
However since we're submitting asynchronous requests we sometimes have
one that completes before we submit the next one, so we end up calling
complete on the nfs_direct_request twice.
The only other place we use nfs_generic_commit_list() is in
__nfs_commit_inode, which wraps this call in a
nfs_commit_begin();
nfs_commit_end();
Which is a common pattern for this style of completion handling, one
that is also repeated in the direct code with get_dreq()/put_dreq()
calls around where we process events as well as in the completion paths.
Fix this by using the same pattern for the commit requests.
Before with my 200 node rocksdb stress running this warning would pop
every 10ish minutes. With my patch the stress test has been running for
several hours without popping.

Title
ext4: avoid online resizing failures due to oversized flex bg
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid online resizing failures due to oversized flex bg
When we online resize an ext4 filesystem with a oversized flexbg_size,
mkfs.ext4 -F -G 67108864 $dev -b 4096 100M
mount $dev $dir
resize2fs $dev 16G
the following WARN_ON is triggered:
==================================================================
WARNING: CPU: 0 PID: 427 at mm/page_alloc.c:4402 __alloc_pages+0x411/0x550
Modules linked in: sg(E)
CPU: 0 PID: 427 Comm: resize2fs Tainted: G E 6.6.0-rc5+ #314
RIP: 0010:__alloc_pages+0x411/0x550
Call Trace:
<TASK>

__x64_sys_ioctl+0xf0/0x150
do_syscall_64+0x3b/0x90
==================================================================
This is because flexbg_size is too large and the size of the new_group_data
array to be allocated exceeds MAX_ORDER. Currently, the minimum value of
MAX_ORDER is 8, the minimum value of PAGE_SIZE is 4096, the corresponding
maximum number of groups that can be allocated is:
(PAGE_SIZE << MAX_ORDER) / sizeof(struct ext4_new_group_data) ≈ 21845
And the value that is down-aligned to the power of 2 is 16384. Therefore,
this value is defined as MAX_RESIZE_BG, and the number of groups added
each time does not exceed this value during resizing, and is added multiple
times to complete the online resizing. The difference is that the metadata
in a flex_bg may be more dispersed.

Title
SUNRPC: fix a memleak in gss_import_v2_context
Summary
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix a memleak in gss_import_v2_context
The ctx->mech_used.data allocated by kmemdup is not freed in neither
gss_import_v2_context nor it only caller gss_krb5_import_sec_context,
which frees ctx on error.
Thus, this patch reform the last call of gss_import_v2_context to the
gss_krb5_import_ctx_v2, preventing the memleak while keepping the return
formation.
Severity ?

Title
isdn: mISDN: netjet: Fix crash in nj_probe:
Summary
In the Linux kernel, the following vulnerability has been resolved:
isdn: mISDN: netjet: Fix crash in nj_probe:
'nj_setup' in netjet.c might fail with -EIO and in this case
'card->irq' is initialized and is bigger than zero. A subsequent call to
'nj_release' will free the irq that has not been requested.
Fix this bug by deleting the previous assignment to 'card->irq' and just
keep the assignment before 'request_irq'.
The KASAN's log reveals it:

Title
tty: n_gsm: fix possible out-of-bounds in gsm0_receive()
Summary
In the Linux kernel, the following vulnerability has been resolved:
tty: n_gsm: fix possible out-of-bounds in gsm0_receive()
Assuming the following:
- side A configures the n_gsm in basic option mode
- side B sends the header of a basic option mode frame with data length 1
- side A switches to advanced option mode
- side B sends 2 data bytes which exceeds gsm->len
Reason: gsm->len is not used in advanced option mode.
- side A switches to basic option mode
- side B keeps sending until gsm0_receive() writes past gsm->buf
Reason: Neither gsm->state nor gsm->len have been reset after
reconfiguration.
Fix this by changing gsm->count to gsm->len comparison from equal to less
than. Also add upper limit checks against the constant MAX_MRU in
gsm0_receive() and gsm1_receive() to harden against memory corruption of
gsm->len and gsm->mru.
All other checks remain as we still need to limit the data according to the
user configuration and actual payload size.

Title
stmmac: Clear variable when destroying workqueue
Summary
In the Linux kernel, the following vulnerability has been resolved:
stmmac: Clear variable when destroying workqueue
Currently when suspending driver and stopping workqueue it is checked whether
workqueue is not NULL and if so, it is destroyed.
Function destroy_workqueue() does drain queue and does clear variable, but
it does not set workqueue variable to NULL. This can cause kernel/module
panic if code attempts to clear workqueue that was not initialized.
This scenario is possible when resuming suspended driver in stmmac_resume(),
because there is no handling for failed stmmac_hw_setup(),
which can fail and return if DMA engine has failed to initialize,
and workqueue is initialized after DMA engine.
Should DMA engine fail to initialize, resume will proceed normally,
but interface won't work and TX queue will eventually timeout,
causing 'Reset adapter' error.
This then does destroy workqueue during reset process.
And since workqueue is initialized after DMA engine and can be skipped,
it will cause kernel/module panic.
To secure against this possible crash, set workqueue variable to NULL when
destroying workqueue.
Log/backtrace from crash goes as follows:

Title
wifi: iwlwifi: mvm: don't set the MFP flag for the GTK
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't set the MFP flag for the GTK
The firmware doesn't need the MFP flag for the GTK, it can even make the
firmware crash. in case the AP is configured with: group cipher TKIP and
MFPC. We would send the GTK with cipher = TKIP and MFP which is of course
not possible.
Severity ?
No CVSS data available.

Title
atl1c: Work around the DMA RX overflow issue
Summary
In the Linux kernel, the following vulnerability has been resolved:
atl1c: Work around the DMA RX overflow issue
This is based on alx driver commit 881d0327db37 ("net: alx: Work around
the DMA RX overflow issue").
The alx and atl1c drivers had RX overflow error which was why a custom
allocator was created to avoid certain addresses. The simpler workaround
then created for alx driver, but not for atl1c due to lack of tester.
Instead of using a custom allocator, check the allocated skb address and
use skb_reserve() to move away from problematic 0x...fc0 address.
Tested on AR8131 on Acer 4540.
Severity ?
No CVSS data available.

Title
pinctrl: core: delete incorrect free in pinctrl_enable()
Summary
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: core: delete incorrect free in pinctrl_enable()
The "pctldev" struct is allocated in devm_pinctrl_register_and_init().
It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(),
so freeing it in pinctrl_enable() will lead to a double free.
The devm_pinctrl_dev_release() function frees the pindescs and destroys
the mutex as well.
Severity ?

Title
net/sched: flower: Fix chain template offload
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: flower: Fix chain template offload
When a qdisc is deleted from a net device the stack instructs the
underlying driver to remove its flow offload callback from the
associated filter block using the 'FLOW_BLOCK_UNBIND' command. The stack
then continues to replay the removal of the filters in the block for
this driver by iterating over the chains in the block and invoking the
'reoffload' operation of the classifier being used. In turn, the
classifier in its 'reoffload' operation prepares and emits a
'FLOW_CLS_DESTROY' command for each filter.
However, the stack does not do the same for chain templates and the
underlying driver never receives a 'FLOW_CLS_TMPLT_DESTROY' command when
a qdisc is deleted. This results in a memory leak [1] which can be
reproduced using [2].
Fix by introducing a 'tmplt_reoffload' operation and have the stack
invoke it with the appropriate arguments as part of the replay.
Implement the operation in the sole classifier that supports chain
templates (flower) by emitting the 'FLOW_CLS_TMPLT_{CREATE,DESTROY}'
command based on whether a flow offload callback is being bound to a
filter block or being unbound from one.
As far as I can tell, the issue happens since cited commit which
reordered tcf_block_offload_unbind() before tcf_block_flush_all_chains()
in __tcf_block_put(). The order cannot be reversed as the filter block
is expected to be freed after flushing all the chains.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: flower: Fix chain template offload\n\nWhen a qdisc is deleted from a net device the stack instructs the\nunderlying driver to remove its flow offload callback from the\nassociated filter block using the \u0027FLOW_BLOCK_UNBIND\u0027 command. The stack\nthen continues to replay the removal of the filters in the block for\nthis driver by iterating over the chains in the block and invoking the\n\u0027reoffload\u0027 operation of the classifier being used. In turn, the\nclassifier in its \u0027reoffload\u0027 operation prepares and emits a\n\u0027FLOW_CLS_DESTROY\u0027 command for each filter.\n\nHowever, the stack does not do the same for chain templates and the\nunderlying driver never receives a \u0027FLOW_CLS_TMPLT_DESTROY\u0027 command when\na qdisc is deleted. This results in a memory leak [1] which can be\nreproduced using [2].\n\nFix by introducing a \u0027tmplt_reoffload\u0027 operation and have the stack\ninvoke it with the appropriate arguments as part of the replay.\nImplement the operation in the sole classifier that supports chain\ntemplates (flower) by emitting the \u0027FLOW_CLS_TMPLT_{CREATE,DESTROY}\u0027\ncommand based on whether a flow offload callback is being bound to a\nfilter block or being unbound from one.\n\nAs far as I can tell, the issue happens since cited commit which\nreordered tcf_block_offload_unbind() before tcf_block_flush_all_chains()\nin __tcf_block_put(). The order cannot be reversed as the filter block\nis expected to be freed after flushing all the chains.\n\n[1]\nunreferenced object 0xffff888107e28800 (size 2048):\n comm \"tc\", pid 1079, jiffies 4294958525 (age 3074.287s)\n hex dump (first 32 bytes):\n b1 a6 7c 11 81 88 ff ff e0 5b b3 10 81 88 ff ff ..|......[......\n 01 00 00 00 00 00 00 00 e0 aa b0 84 ff ff ff ff ................\n backtrace:\n [\u003cffffffff81c06a68\u003e] __kmem_cache_alloc_node+0x1e8/0x320\n [\u003cffffffff81ab374e\u003e] __kmalloc+0x4e/0x90\n [\u003cffffffff832aec6d\u003e] mlxsw_sp_acl_ruleset_get+0x34d/0x7a0\n [\u003cffffffff832bc195\u003e] mlxsw_sp_flower_tmplt_create+0x145/0x180\n [\u003cffffffff832b2e1a\u003e] mlxsw_sp_flow_block_cb+0x1ea/0x280\n [\u003cffffffff83a10613\u003e] tc_setup_cb_call+0x183/0x340\n [\u003cffffffff83a9f85a\u003e] fl_tmplt_create+0x3da/0x4c0\n [\u003cffffffff83a22435\u003e] tc_ctl_chain+0xa15/0x1170\n [\u003cffffffff838a863c\u003e] rtnetlink_rcv_msg+0x3cc/0xed0\n [\u003cffffffff83ac87f0\u003e] netlink_rcv_skb+0x170/0x440\n [\u003cffffffff83ac6270\u003e] netlink_unicast+0x540/0x820\n [\u003cffffffff83ac6e28\u003e] netlink_sendmsg+0x8d8/0xda0\n [\u003cffffffff83793def\u003e] ____sys_sendmsg+0x30f/0xa80\n [\u003cffffffff8379d29a\u003e] ___sys_sendmsg+0x13a/0x1e0\n [\u003cffffffff8379d50c\u003e] __sys_sendmsg+0x11c/0x1f0\n [\u003cffffffff843b9ce0\u003e] do_syscall_64+0x40/0xe0\nunreferenced object 0xffff88816d2c0400 (size 1024):\n comm \"tc\", pid 1079, jiffies 4294958525 (age 3074.287s)\n hex dump (first 32 bytes):\n 40 00 00 00 00 00 00 00 57 f6 38 be 00 00 00 00 @.......W.8.....\n 10 04 2c 6d 81 88 ff ff 10 04 2c 6d 81 88 ff ff ..,m......,m....\n backtrace:\n [\u003cffffffff81c06a68\u003e] __kmem_cache_alloc_node+0x1e8/0x320\n [\u003cffffffff81ab36c1\u003e] __kmalloc_node+0x51/0x90\n [\u003cffffffff81a8ed96\u003e] kvmalloc_node+0xa6/0x1f0\n [\u003cffffffff82827d03\u003e] bucket_table_alloc.isra.0+0x83/0x460\n [\u003cffffffff82828d2b\u003e] rhashtable_init+0x43b/0x7c0\n [\u003cffffffff832aed48\u003e] mlxsw_sp_acl_ruleset_get+0x428/0x7a0\n [\u003cffffffff832bc195\u003e] mlxsw_sp_flower_tmplt_create+0x145/0x180\n [\u003cffffffff832b2e1a\u003e] mlxsw_sp_flow_block_cb+0x1ea/0x280\n [\u003cffffffff83a10613\u003e] tc_setup_cb_call+0x183/0x340\n [\u003cffffffff83a9f85a\u003e] fl_tmplt_create+0x3da/0x4c0\n [\u003cffffffff83a22435\u003e] tc_ctl_chain+0xa15/0x1170\n [\u003cffffffff838a863c\u003e] rtnetlink_rcv_msg+0x3cc/0xed0\n [\u003cffffffff83ac87f0\u003e] netlink_rcv_skb+0x170/0x440\n [\u003cffffffff83ac6270\u003e] netlink_unicast+0x540/0x820\n [\u003cffffffff83ac6e28\u003e] netlink_sendmsg+0x8d8/0xda0\n [\u003cffffffff83793def\u003e] ____sys_sendmsg+0x30f/0xa80\n\n[2]\n # tc qdisc add dev swp1 clsact\n # tc chain add dev swp1 ingress proto ip chain 1 flower dst_ip 0.0.0.0/32\n # tc qdisc del dev\n---truncated---"

TIPC bearer-related names including link names must be null-terminated
strings. If a link name which is not null-terminated is passed through
netlink, strstr() and similar functions can cause buffer overrun. This
causes the above issue.
This patch changes the nla_policy for bearer-related names from NLA_STRING
to NLA_NUL_STRING. This resolves the issue by ensuring that only
null-terminated strings are accepted as bearer-related names.
syzbot reported similar uninit-value issue related to bearer names [2]. The
root cause of this issue is that a non-null-terminated bearer name was
passed. This patch also resolved this issue.

Title
virtio-blk: fix implicit overflow on virtio_max_dma_size
Summary
In the Linux kernel, the following vulnerability has been resolved:
virtio-blk: fix implicit overflow on virtio_max_dma_size
The following codes have an implicit conversion from size_t to u32:
(u32)max_size = (size_t)virtio_max_dma_size(vdev);
This may lead overflow, Ex (size_t)4G -> (u32)0. Once
virtio_max_dma_size() has a larger size than U32_MAX, use U32_MAX
instead.
Severity ?
No CVSS data available.

Title
quota: Fix potential NULL pointer dereference
Summary
In the Linux kernel, the following vulnerability has been resolved:
quota: Fix potential NULL pointer dereference
Below race may cause NULL pointer dereference
P1 P2
dquot_free_inode quota_off
drop_dquot_ref
remove_dquot_ref
dquots = i_dquot(inode)
dquots = i_dquot(inode)
srcu_read_lock
dquots[cnt]) != NULL (1)
dquots[type] = NULL (2)
spin_lock(&dquots[cnt]->dq_dqb_lock) (3)
....
If dquot_free_inode(or other routines) checks inode's quota pointers (1)
before quota_off sets it to NULL(2) and use it (3) after that, NULL pointer
dereference will be triggered.
So let's fix it by using a temporary pointer to avoid this issue.
Severity ?
