CVE-2023-52498 (GCVE-0-2023-52498)

Title
PM: sleep: Fix possible deadlocks in core system-wide PM code
Summary
In the Linux kernel, the following vulnerability has been resolved:
PM: sleep: Fix possible deadlocks in core system-wide PM code
It is reported that in low-memory situations the system-wide resume core
code deadlocks, because async_schedule_dev() executes its argument
function synchronously if it cannot allocate memory (and not only in
that case) and that function attempts to acquire a mutex that is already
held. Executing the argument function synchronously from within
dpm_async_fn() may also be problematic for ordering reasons (it may
cause a consumer device's resume callback to be invoked before a
requisite supplier device's one, for example).
Address this by changing the code in question to use
async_schedule_dev_nocall() for scheduling the asynchronous
execution of device suspend and resume functions and to directly
run them synchronously if async_schedule_dev_nocall() returns false.
Severity

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPM: sleep: Fix possible deadlocks in core system-wide PM code\n\nIt is reported that in low-memory situations the system-wide resume core\ncode deadlocks, because async_schedule_dev() executes its argument\nfunction synchronously if it cannot allocate memory (and not only in\nthat case) and that function attempts to acquire a mutex that is already\nheld. Executing the argument function synchronously from within\ndpm_async_fn() may also be problematic for ordering reasons (it may\ncause a consumer device\u0027s resume callback to be invoked before a\nrequisite supplier device\u0027s one, for example).\n\nAddress this by changing the code in question to use\nasync_schedule_dev_nocall() for scheduling the asynchronous\nexecution of device suspend and resume functions and to directly\nrun them synchronously if async_schedule_dev_nocall() returns false."

Title
wifi: mac80211: fix potential key use-after-free
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix potential key use-after-free
When ieee80211_key_link() is called by ieee80211_gtk_rekey_add()
but returns 0 due to KRACK protection (identical key reinstall),
ieee80211_gtk_rekey_add() will still return a pointer into the
key, in a potential use-after-free. This normally doesn't happen
since it's only called by iwlwifi in case of WoWLAN rekey offload
which has its own KRACK protection, but still better to fix, do
that by returning an error code and converting that to success on
the cfg80211 boundary only, leaving the error for bad callers of
ieee80211_gtk_rekey_add().

Title
nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()
Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()
In nilfs_gccache_submit_read_data(), brelse(bh) is called to drop the
reference count of bh when the call to nilfs_dat_translate() fails. If
the reference count hits 0 and its owner page gets unlocked, bh may be
freed. However, bh->b_page is dereferenced to put the page after that,
which may result in a use-after-free bug. This patch moves the release
operation after unlocking and putting the page.
NOTE: The function in question is only called in GC, and in combination
with current userland tools, address translation using DAT does not occur
in that function, so the code path that causes this issue will not be
executed. However, it is possible to run that code path by intentionally
modifying the userland GC library or by calling the GC ioctl directly.

Title
ceph: fix deadlock or deadcode of misusing dget()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ceph: fix deadlock or deadcode of misusing dget()
The lock order is incorrect between denty and its parent, we should
always make sure that the parent get the lock first.
But since this deadcode is never used and the parent dir will always
be set from the callers, let's just remove it.

Title
IB/ipoib: Fix mcast list locking
Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/ipoib: Fix mcast list locking
Releasing the `priv->lock` while iterating the `priv->multicast_list` in
`ipoib_mcast_join_task()` opens a window for `ipoib_mcast_dev_flush()` to
remove the items while in the middle of iteration. If the mcast is removed
while the lock was dropped, the for loop spins forever resulting in a hard
lockup (as was reported on RHEL 4.18.0-372.75.1.el8_6 kernel):
Task A (kworker/u72:2 below) | Task B (kworker/u72:0 below)
-----------------------------------+-----------------------------------
ipoib_mcast_join_task(work) | ipoib_ib_dev_flush_light(work)
spin_lock_irq(&priv->lock) | __ipoib_ib_dev_flush(priv, ...)
list_for_each_entry(mcast, | ipoib_mcast_dev_flush(dev = priv->dev)
&priv->multicast_list, list) |
ipoib_mcast_join(dev, mcast) |
spin_unlock_irq(&priv->lock) |
| spin_lock_irqsave(&priv->lock, flags)
| list_for_each_entry_safe(mcast, tmcast,
| &priv->multicast_list, list)
| list_del(&mcast->list);
| list_add_tail(&mcast->list, &remove_list)
| spin_unlock_irqrestore(&priv->lock, flags)
spin_lock_irq(&priv->lock) |
| ipoib_mcast_remove_list(&remove_list)
(Here, `mcast` is no longer on the | list_for_each_entry_safe(mcast, tmcast,
`priv->multicast_list` and we keep | remove_list, list)
spinning on the `remove_list` of | >>> wait_for_completion(&mcast->done)
the other thread which is blocked |
and the list is still valid on |
it's stack.)
Fix this by keeping the lock held and changing to GFP_ATOMIC to prevent
eventual sleeps.
Unfortunately we could not reproduce the lockup and confirm this fix but
based on the code review I think this fix should address such lockups.

f2fs: fix to tag gcing flag on page during block migration
Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to tag gcing flag on page during block migration
It needs to add missing gcing flag on page during block migration,
in order to garantee migrated data be persisted during checkpoint,
otherwise out-of-order persistency between data and node may cause
data corruption after SPOR.
Similar issue was fixed by commit 2d1fe8a86bf5 ("f2fs: fix to tag
gcing flag on page during file defragment").

wifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus()
Fix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug
occurs when txs->cnt, data from a URB provided by a USB device, is
bigger than the size of the array txs->txstatus, which is
HTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug
handling code after the check. Make the function return if that is the
case.
Found by a modified version of syzkaller.
UBSAN: array-index-out-of-bounds in htc_drv_txrx.c
index 13 is out of range for type '__wmi_event_txstatus [12]'
Call Trace:
ath9k_htc_txstatus
ath9k_wmi_event_tasklet
tasklet_action_common
__do_softirq

Title
wifi: rt2x00: restart beacon queue when hardware reset
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rt2x00: restart beacon queue when hardware reset
When a hardware reset is triggered, all registers are reset, so all
queues are forced to stop in hardware interface. However, mac80211
will not automatically stop the queue. If we don't manually stop the
beacon queue, the queue will be deadlocked and unable to start again.
This patch fixes the issue where Apple devices cannot connect to the
AP after calling ieee80211_restart_hw().

Title
KVM: s390: fix setting of fpc register
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: fix setting of fpc register
kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control
(fpc) register of a guest cpu. The new value is tested for validity by
temporarily loading it into the fpc register.
This may lead to corruption of the fpc register of the host process:
if an interrupt happens while the value is temporarily loaded into the fpc
register, and within interrupt context floating point or vector registers
are used, the current fp/vx registers are saved with save_fpu_regs()
assuming they belong to user space and will be loaded into fp/vx registers
when returning to user space.
test_fp_ctl() restores the original user space / host process fpc register
value, however it will be discarded, when returning to user space.
In result the host process will incorrectly continue to run with the value
that was supposed to be used for a guest cpu.
Fix this by simply removing the test. There is another test right before
the SIE context is entered which will handles invalid values.
This results in a change of behaviour: invalid values will now be accepted
instead of that the ioctl fails with -EINVAL. This seems to be acceptable,
given that this interface is most likely not used anymore, and this is in
addition the same behaviour implemented with the memory mapped interface
(replace invalid values with zero) - see sync_regs() in kvm-s390.c.
