Title
bnxt_re: avoid shift undefined behavior in bnxt_qplib_alloc_init_hwq
Summary
In the Linux kernel, the following vulnerability has been resolved:
bnxt_re: avoid shift undefined behavior in bnxt_qplib_alloc_init_hwq
Undefined behavior is triggered when bnxt_qplib_alloc_init_hwq is called
with hwq_attr->aux_depth != 0 and hwq_attr->aux_stride == 0.
In that case, "roundup_pow_of_two(hwq_attr->aux_stride)" gets called.
roundup_pow_of_two is documented as undefined for 0.
Fix it in the one caller that had this combination.
The undefined behavior was detected by UBSAN:
UBSAN: shift-out-of-bounds in ./include/linux/log2.h:57:13
shift exponent 64 is too large for 64-bit type 'long unsigned int'
CPU: 24 PID: 1075 Comm: (udev-worker) Not tainted 6.9.0-rc6+ #4
Hardware name: Abacus electric, s.r.o. - servis@abacus.cz Super Server/H12SSW-iN, BIOS 2.7 10/25/2023

Title
net: fec: remove .ndo_poll_controller to avoid deadlocks
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fec: remove .ndo_poll_controller to avoid deadlocks
There is a deadlock issue found in sungem driver, please refer to the
commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid
deadlocks"). The root cause of the issue is that netpoll is in atomic
context and disable_irq() is called by .ndo_poll_controller interface
of sungem driver, however, disable_irq() might sleep. After analyzing
the implementation of fec_poll_controller(), the fec driver should have
the same issue. Due to the fec driver uses NAPI for TX completions, the
.ndo_poll_controller is unnecessary to be implemented in the fec driver,
so fec_poll_controller() can be safely removed.

Title
io_uring: fix possible deadlock in io_register_iowq_max_workers()
Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix possible deadlock in io_register_iowq_max_workers()
The io_register_iowq_max_workers() function calls io_put_sq_data(),
which acquires the sqd->lock without releasing the uring_lock.
Similar to the commit 009ad9f0c6ee ("io_uring: drop ctx->uring_lock
before acquiring sqd->lock"), this can lead to a potential deadlock
situation.
To resolve this issue, the uring_lock is released before calling
io_put_sq_data(), and then it is re-acquired after the function call.
This change ensures that the locks are acquired in the correct
order, preventing the possibility of a deadlock.
Severity
No CVSS data available.

CVE-2024-43868 (GCVE-0-2024-43868)

Title
riscv/purgatory: align riscv_kernel_entry
Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv/purgatory: align riscv_kernel_entry
When alignment handling is delegated to the kernel, everything must be
word-aligned in purgatory, since the trap handler is then set to the
kexec one. Without the alignment, hitting the exception would
ultimately crash. On other occasions, the kernel's handler would take
care of exceptions.
This has been tested on a JH7110 SoC with oreboot and its SBI delegating
unaligned access exceptions and the kernel configured to handle them.
Severity
No CVSS data available.

Title
drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencing
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencing
This commit adds null checks for the 'stream' and 'plane' variables in
the dcn30_apply_idle_power_optimizations function. These variables were
previously assumed to be null at line 922, but they were used later in
the code without checking if they were null. This could potentially lead
to a null pointer dereference, which would cause a crash.
The null checks ensure that 'stream' and 'plane' are not null before
they are used, preventing potential crashes.
Fixes the below static smatch checker:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:938 dcn30_apply_idle_power_optimizations() error: we previously assumed 'stream' could be null (see line 922)
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:940 dcn30_apply_idle_power_optimizations() error: we previously assumed 'plane' could be null (see line 922)

Title
wifi: mac80211: fix NULL dereference at band check in starting tx ba session
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix NULL dereference at band check in starting tx ba session
In MLD connection, link_data/link_conf are dynamically allocated. They
don't point to vif->bss_conf. So, there will be no chanreq assigned to
vif->bss_conf and then the chan will be NULL. Tweak the code to check
ht_supported/vht_supported/has_he/has_eht on sta deflink.

Title
parisc: fix a possible DMA corruption
Summary
In the Linux kernel, the following vulnerability has been resolved:
parisc: fix a possible DMA corruption
ARCH_DMA_MINALIGN was defined as 16 - this is too small - it may be
possible that two unrelated 16-byte allocations share a cache line. If
one of these allocations is written using DMA and the other is written
using cached write, the value that was written with DMA may be
corrupted.
This commit changes ARCH_DMA_MINALIGN to be 128 on PA20 and 32 on PA1.1 -
that's the largest possible cache line size.
As different parisc microarchitectures have different cache line size, we
define arch_slab_minalign(), cache_line_size() and
dma_get_cache_alignment() so that the kernel may tune slab cache
parameters dynamically, based on the detected cache line size.

Title
ext4: fix timer use-after-free on failed mount
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix timer use-after-free on failed mount
Syzbot has found an ODEBUG bug in ext4_fill_super
The del_timer_sync function cancels the s_err_report timer,
which reminds about filesystem errors daily. We should
guarantee the timer is no longer active before kfree(sbi).
When filesystem mounting fails, the flow goes to failed_mount3,
where an error occurs when ext4_stop_mmpd is called, causing
a read I/O failure. This triggers the ext4_handle_error function
that ultimately re-arms the timer,
leaving the s_err_report timer active before kfree(sbi) is called.
Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix timer use-after-free on failed mount\n\nSyzbot has found an ODEBUG bug in ext4_fill_super\n\nThe del_timer_sync function cancels the s_err_report timer,\nwhich reminds about filesystem errors daily. We should\nguarantee the timer is no longer active before kfree(sbi).\n\nWhen filesystem mounting fails, the flow goes to failed_mount3,\nwhere an error occurs when ext4_stop_mmpd is called, causing\na read I/O failure. This triggers the ext4_handle_error function\nthat ultimately re-arms the timer,\nleaving the s_err_report timer active before kfree(sbi) is called.\n\nFix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd."
