Title
RDMA/mlx5: Fix mlx5_poll_one() cur_qp update flow
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix mlx5_poll_one() cur_qp update flow
When cur_qp isn't NULL, in order to avoid fetching the QP from
the radix tree again we check if the next cqe QP is identical to
the one we already have.
The bug however is that we are checking if the QP is identical by
checking the QP number inside the CQE against the QP number inside the
mlx5_ib_qp, but that's wrong since the QP number from the CQE is from
FW so it should be matched against mlx5_core_qp which is our FW QP
number.
Otherwise we could use the wrong QP when handling a CQE which could
cause the kernel trace below.
This issue is mainly noticeable over QPs 0 & 1, since for now they are
the only QPs in our driver whereas the QP number inside mlx5_ib_qp
doesn't match the QP number inside mlx5_core_qp.

No memory layout or timing condition outside the attacker\u0027s influence must be met.\nPR:N - MAD reception on QP0/QP1 is completely unauthenticated \u2014 any node on the subnet can send MADs that land on the GSI/SMI receive queues and generate CQEs. The polling itself runs in an unbound kernel workqueue with no credential check.\nUI:N - The ib_mad port, its QP0/QP1 pair, and the shared CQ are created automatically when the mlx5 IB device is probed; no administrator or victim action is needed to arm or trigger the path.\nS:U - The wrong-QP handling, out-of-bounds accesses, and the resulting indirect call all occur within the kernel\u0027s own security authority.

Title
RDMA/core: Don't expose hw_counters outside of init net namespace
Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Don't expose hw_counters outside of init net namespace
Commit 467f432a521a ("RDMA/core: Split port and device counter sysfs
attributes") accidentally almost exposed hw counters to non-init net
namespaces. It didn't expose them fully, as an attempt to read any of
those counters leads to a crash like this one:

The problem can be reproduced using the following steps:
ip netns add foo
ip netns exec foo bash
cat /sys/class/infiniband/mlx4_0/hw_counters/*
The panic occurs because of casting the device pointer into an
ib_device pointer using container_of() in hw_stat_device_show() is
wrong and leads to a memory corruption.
However the real problem is that hw counters should never been exposed
outside of the non-init net namespace.
Fix this by saving the index of the corresponding attribute group
(it might be 1 or 2 depending on the presence of driver-specific
attributes) and zeroing the pointer to hw_counters group for compat
devices during the initialization.
With this fix applied hw_counters are not available in a non-init
net namespace:
find /sys/class/infiniband/mlx4_0/ -name hw_counters
/sys/class/infiniband/mlx4_0/ports/1/hw_counters
/sys/class/infiniband/mlx4_0/ports/2/hw_counters
/sys/class/infiniband/mlx4_0/hw_counters
ip netns add foo
ip netns exec foo bash
find /sys/class/infiniband/mlx4_0/ -name hw_counters

No network input reaches the vulnerable code.\nAC:L - The trigger is fully deterministic and requires no race: create a netns, mount sysfs, read the counter file (the commit message documents the exact three-command reproducer). `ib_devices_shared_netns` defaults to true, so no unusual configuration is needed.\nPR:L - An unprivileged local user can reach it via `unshare -Urnm` plus a sysfs mount, since sysfs is `FS_USERNS_MOUNT` and only requires `ns_capable(net-\u003euser_ns, CAP_SYS_ADMIN)`; the counter files are world-readable (0444), so any process inside an ordinary container also qualifies. It is not PR:N because a local account/container foothold is required.\nUI:N - The attacker performs every step itself \u2014 namespace creation, sysfs mount and file read \u2014 with no action by any other user or administrator.\nS:U - The type confusion corrupts kernel memory within the same kernel security authority; no hypervisor, IOMMU or other trust boundary is crossed, matching standard kernel privilege-escalation scoring.\nC:H - The bogus `container_of()` makes the kernel read `hw_stats_data` from uninitialized/adjacent slab memory that heap grooming can control, after which `print_hw_stat()` returns `stats-\u003evalue[index]` \u2014 an attacker-influenced pointer plus index \u2014 to userspace through `sysfs_emit()`, yielding arbitrary kernel memory disclosure.\nI:H - The fabricated `ib_device` pointer produces a wild-pointer write via `mutex_lock(\u0026stats-\u003elock)` and via `set_stats_lifespan()` on the writable `lifespan` attribute, and `update_hw_stats()` performs an indirect call through `dev-\u003eops.get_hw_stats` read from fully out-of-bounds memory, giving a control-flow hijack primitive.\nA:H - The reported and reproducible outcome is an immediate kernel NULL pointer dereference oops/panic in `hw_stat_device_show()`, which any unprivileged user or container process can trigger on demand with a single `cat`."

Title
x86/mm/pat: Fix VM_PAT handling when fork() fails in copy_page_range()
Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm/pat: Fix VM_PAT handling when fork() fails in copy_page_range()
If track_pfn_copy() fails, we already added the dst VMA to the maple
tree. As fork() fails, we'll cleanup the maple tree, and stumble over
the dst VMA for which we neither performed any reservation nor copied
any page tables.
Consequently untrack_pfn() will see VM_PAT and try obtaining the
PAT information from the page table -- which fails because the page
table was not copied.
The easiest fix would be to simply clear the VM_PAT flag of the dst VMA
if track_pfn_copy() fails. However, the whole thing is about "simply"
clearing the VM_PAT flag is shaky as well: if we passed track_pfn_copy()
and performed a reservation, but copying the page tables fails, we'll
simply clear the VM_PAT flag, not properly undoing the reservation ...
which is also wrong.
So let's fix it properly: set the VM_PAT flag only if the reservation
succeeded (leaving it clear initially), and undo the reservation if
anything goes wrong while copying the page tables: clearing the VM_PAT
flag after undoing the reservation.
Note that any copied page table entries will get zapped when the VMA will
get removed later, after copy_page_range() succeeded; as VM_PAT is not set
then, we won't try cleaning VM_PAT up once more and untrack_pfn() will be
happy. Note that leaving these page tables in place without a reservation
is not a problem, as we are aborting fork(); this process will never run.
A reproducer can trigger this usually at the first try:

Likely this case was missed in:
d155df53f310 ("x86/mm/pat: clear VM_PAT if copy_p4d_range failed")
... and instead of undoing the reservation we simply cleared the VM_PAT flag.
Keep the documentation of these functions in include/linux/pgtable.h,
one place is more than sufficient -- we should clean that up for the other
functions like track_pfn_remap/untrack_pfn separately.

Title
PCI: brcmstb: Fix error path after a call to regulator_bulk_get()
Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: brcmstb: Fix error path after a call to regulator_bulk_get()
If the regulator_bulk_get() returns an error and no regulators
are created, we need to set their number to zero.
If we don't do this and the PCIe link up fails, a call to the
regulator_bulk_free() will result in a kernel panic.
While at it, print the error value, as we cannot return an error
upwards as the kernel will WARN() on an error from add_bus().

Title
drm/vkms: Fix use after free and double free on init error
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vkms: Fix use after free and double free on init error
If the driver initialization fails, the vkms_exit() function might
access an uninitialized or freed default_config pointer and it might
double free it.
Fix both possible errors by initializing default_config only when the
driver initialization succeeded.

Title
thermal: int340x: Add NULL check for adev
Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal: int340x: Add NULL check for adev
Not all devices have an ACPI companion fwnode, so adev might be NULL.
This is similar to the commit cd2fd6eab480
("platform/x86: int3472: Check for adev == NULL").
Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in int3402_thermal_probe().
Note, under the same directory, int3400_thermal_probe() has such a
check.

Title
watch_queue: fix pipe accounting mismatch
Summary
In the Linux kernel, the following vulnerability has been resolved:
watch_queue: fix pipe accounting mismatch
Currently, watch_queue_set_size() modifies the pipe buffers charged to
user->pipe_bufs without updating the pipe->nr_accounted on the pipe
itself, due to the if (!pipe_has_watch_queue()) test in
pipe_resize_ring(). This means that when the pipe is ultimately freed,
we decrement user->pipe_bufs by something other than what than we had
charged to it, potentially leading to an underflow. This in turn can
cause subsequent too_many_pipe_buffers_soft() tests to fail with -EPERM.
To remedy this, explicitly account for the pipe usage in
watch_queue_set_size() to match the number set via account_pipe_buffers()
(It's unclear why watch_queue_set_size() does not update nr_accounted;
it may be due to intentional overprovisioning in watch_queue_set_size()?)
Severity
No CVSS data available.

Title
ext4: fix OOB read when checking dotdot dir
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix OOB read when checking dotdot dir
Mounting a corrupted filesystem with directory which contains '.' dir
entry with rec_len == block size results in out-of-bounds read (later
on, when the corrupted directory is removed).
ext4_empty_dir() assumes every ext4 directory contains at least '.'
and '..' as directory entries in the first data block. It first loads
the '.' dir entry, performs sanity checks by calling ext4_check_dir_entry()
and then uses its rec_len member to compute the location of '..' dir
entry (in ext4_next_entry). It assumes the '..' dir entry fits into the
same data block.
If the rec_len of '.' is precisely one block (4KB), it slips through the
sanity checks (it is considered the last directory entry in the data
block) and leaves "struct ext4_dir_entry_2 *de" point exactly past the
memory slot allocated to the data block. The following call to
ext4_check_dir_entry() on new value of de then dereferences this pointer
which results in out-of-bounds mem access.
Fix this by extending __ext4_check_dir_entry() to check for '.' dir
entries that reach the end of data block. Make sure to ignore the phony
dir entries for checksum (by checking name_len for non-zero).
Note: This is reported by KASAN as use-after-free in case another
structure was recently freed from the slot past the bound, but it is
really an OOB read.
This issue was found by syzkaller tool.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix OOB read when checking dotdot dir\n\nMounting a corrupted filesystem with directory which contains \u0027.\u0027 dir\nentry with rec_len == block size results in out-of-bounds read (later\non, when the corrupted directory is removed).\n\next4_empty_dir() assumes every ext4 directory contains at least \u0027.\u0027\nand \u0027..\u0027 as directory entries in the first data block. It first loads\nthe \u0027.\u0027 dir entry, performs sanity checks by calling ext4_check_dir_entry()\nand then uses its rec_len member to compute the location of \u0027..\u0027 dir\nentry (in ext4_next_entry). It assumes the \u0027..\u0027 dir entry fits into the\nsame data block.\n\nIf the rec_len of \u0027.\u0027 is precisely one block (4KB), it slips through the\nsanity checks (it is considered the last directory entry in the data\nblock) and leaves \"struct ext4_dir_entry_2 *de\" point exactly past the\nmemory slot allocated to the data block. The following call to\next4_check_dir_entry() on new value of de then dereferences this pointer\nwhich results in out-of-bounds mem access.\n\nFix this by extending __ext4_check_dir_entry() to check for \u0027.\u0027 dir\nentries that reach the end of data block. Make sure to ignore the phony\ndir entries for checksum (by checking name_len for non-zero).\n\nNote: This is reported by KASAN as use-after-free in case another\nstructure was recently freed from the slot past the bound, but it is\nreally an OOB read.\n\nThis issue was found by syzkaller tool.\n\nCall Trace:\n[ 38.594108] BUG: KASAN: slab-use-after-free in __ext4_check_dir_entry+0x67e/0x710\n[ 38.594649] Read of size 2 at addr ffff88802b41a004 by task syz-executor/5375\n[ 38.595158]\n[ 38.595288] CPU: 0 UID: 0 PID: 5375 Comm: syz-executor Not tainted 6.14.0-rc7 #1\n[ 38.595298] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014\n[ 38.595304] Call Trace:\n[ 38.595308] \u003cTASK\u003e\n[ 38.595311] dump_stack_lvl+0xa7/0xd0\n[ 38.595325] print_address_description.constprop.0+0x2c/0x3f0\n[ 38.595339] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595349] print_report+0xaa/0x250\n[ 38.595359] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595368] ? kasan_addr_to_slab+0x9/0x90\n[ 38.595378] kasan_report+0xab/0xe0\n[ 38.595389] ? __ext4_check_dir_entry+0x67e/0x710\n[ 38.595400] __ext4_check_dir_entry+0x67e/0x710\n[ 38.595410] ext4_empty_dir+0x465/0x990\n[ 38.595421] ? __pfx_ext4_empty_dir+0x10/0x10\n[ 38.595432] ext4_rmdir.part.0+0x29a/0xd10\n[ 38.595441] ? __dquot_initialize+0x2a7/0xbf0\n[ 38.595455] ? __pfx_ext4_rmdir.part.0+0x10/0x10\n[ 38.595464] ? __pfx___dquot_initialize+0x10/0x10\n[ 38.595478] ? down_write+0xdb/0x140\n[ 38.595487] ? __pfx_down_write+0x10/0x10\n[ 38.595497] ext4_rmdir+0xee/0x140\n[ 38.595506] vfs_rmdir+0x209/0x670\n[ 38.595517] ? lookup_one_qstr_excl+0x3b/0x190\n[ 38.595529] do_rmdir+0x363/0x3c0\n[ 38.595537] ? __pfx_do_rmdir+0x10/0x10\n[ 38.595544] ? strncpy_from_user+0x1ff/0x2e0\n[ 38.595561] __x64_sys_unlinkat+0xf0/0x130\n[ 38.595570] do_syscall_64+0x5b/0x180\n[ 38.595583] entry_SYSCALL_64_after_hwframe+0x76/0x7e"

Local attack vector scores higher than physical and correctly models USB/auto-mount and loop-mount delivery.\nAC:L - The condition is fully deterministic and entirely attacker-authored \u2014 setting the `.` entry\u0027s `rec_len` to exactly the block size in the image reliably slips past every sanity check in `__ext4_check_dir_entry()` and lands `de` past the block on every attempt. No race, timing, or uncontrolled memory-layout requirement.\nPR:L - Once the image is mounted (via udisks2/GNOME auto-mount of removable media on desktops and kiosks, or an fstab `user` entry), any unprivileged local user with ordinary access to the mount can invoke `rmdir` and reach `ext4_empty_dir()`; no capability check gates the path.\nUI:N - In the auto-mount scenario the attacker performs both steps themselves \u2014 inserting the media triggers the mount automatically and the same attacker issues the `rmdir` \u2014 so no action by a separate user is required.\nS:U - The out-of-bounds access, the disclosure, and the panic all occur within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The read reaches into the adjacent slab object/page and its contents are exfiltrated to userspace-visible dmesg through `ext4_error_inode()`, which prints the out-of-bounds `inode` and `rec_len` fields verbatim. The operation is cheaply repeatable and the neighbouring slot can be heap-groomed, making it a practical kernel heap/pointer disclosure primitive rather than a bounded one-shot leak.\nI:H - Data read out of bounds directly controls subsequent logic \u2014 if the adjacent heap bytes decode as a valid `..` entry, `ext4_empty_dir()` wrongly reports the directory empty and `rmdir`/`rename` proceeds to unlink a non-empty directory, and the OOB `rec_len` drives the following offset walk. KASAN classifies the access as a use-after-free on the neighbouring freed object, so attacker-groomed heap state translates into corrupted filesystem-metadata operations.\nA:H - The error path is reached with the attacker-controlled superblock, and `s_errors = EXT4_ERRORS_PANIC` (`fs/ext4/super.c:4364`) makes `ext4_error_inode()` call `panic()` at `super.c:735`, giving a guaranteed kernel panic. Independently, the read past the block can fault on an unmapped or poisoned page, and on debug/KASAN kernels it is an immediate BUG."

Title
HSI: ssi_protocol: Fix use after free vulnerability in ssi_protocol Driver Due to Race Condition
Summary
In the Linux kernel, the following vulnerability has been resolved:
HSI: ssi_protocol: Fix use after free vulnerability in ssi_protocol Driver Due to Race Condition
In the ssi_protocol_probe() function, &ssi->work is bound with
ssip_xmit_work(), In ssip_pn_setup(), the ssip_pn_xmit() function
within the ssip_pn_ops structure is capable of starting the
work.
If we remove the module which will call ssi_protocol_remove()
to make a cleanup, it will free ssi through kfree(ssi),
while the work mentioned above will be used. The sequence
of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| ssip_xmit_work
ssi_protocol_remove |
kfree(ssi); |
| struct hsi_client *cl = ssi->cl;
| // use ssi
Fix it by ensuring that the work is canceled before proceeding
with the cleanup in ssi_protocol_remove().

Title
objtool, media: dib8000: Prevent divide-by-zero in dib8000_set_dds()
Summary
In the Linux kernel, the following vulnerability has been resolved:
objtool, media: dib8000: Prevent divide-by-zero in dib8000_set_dds()
If dib8000_set_dds()'s call to dib8000_read32() returns zero, the result
is a divide-by-zero. Prevent that from happening.
Fixes the following warning with an UBSAN kernel:
drivers/media/dvb-frontends/dib8000.o: warning: objtool: dib8000_tune() falls through to next function dib8096p_cfg_DibRx()
