In the Linux kernel, the following vulnerability has been resolved:
LoongArch: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK
When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS is selected,
cpu_max_bits_warn() generates a runtime warning similar as below while
we show /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit)
instead of NR_CPUS to iterate CPUs.

In the Linux kernel, the following vulnerability has been resolved:
drm/gma500: Fix BUG: sleeping function called from invalid context errors
gma_crtc_page_flip() was holding the event_lock spinlock while calling
crtc_funcs->mode_set_base() which takes ww_mutex.
The only reason to hold event_lock is to clear gma_crtc->page_flip_event
on mode_set_base() errors.
Instead unlock it after setting gma_crtc->page_flip_event and on
errors re-take the lock and clear gma_crtc->page_flip_event it
it is still set.
This fixes the following WARN/stacktrace:

In the Linux kernel, the following vulnerability has been resolved:
drm/msm/mdp5: Fix global state lock backoff
We need to grab the lock after the early return for !hwpipe case.
Otherwise, we could have hit contention yet still returned 0.
Fixes an issue that the new CONFIG_DRM_DEBUG_MODESET_LOCK stuff flagged
in CI:

In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix reset error handling
Do not call iavf_close in iavf_reset_task error handling. Doing so can
lead to double call of napi_disable, which can lead to deadlock there.
Removing VF would lead to iavf_remove task being stuck, because it
requires crit_lock, which is held by iavf_close.
Call iavf_disable_vf if reset fail, so that driver will clean up
remaining invalid resources.
During rapid VF resets, HW can fail to setup VF mailbox. Wrong
error handling can lead to iavf_remove being stuck with:

In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix NULL pointer dereference in is_ftrace_trampoline when ftrace is dead
ftrace_startup does not remove ops from ftrace_ops_list when
ftrace_startup_enable fails:
register_ftrace_function
ftrace_startup
__register_ftrace_function
...
add_ftrace_ops(&ftrace_ops_list, ops)
...
...
ftrace_startup_enable // if ftrace failed to modify, ftrace_disabled is set to 1
...
return 0 // ops is in the ftrace_ops_list.
When ftrace_disabled = 1, unregister_ftrace_function simply returns without doing anything:
unregister_ftrace_function
ftrace_shutdown
if (unlikely(ftrace_disabled))
return -ENODEV; // return here, __unregister_ftrace_function is not executed,
// as a result, ops is still in the ftrace_ops_list
__unregister_ftrace_function
...
If ops is dynamically allocated, it will be free later, in this case,
is_ftrace_trampoline accesses NULL pointer:
is_ftrace_trampoline
ftrace_ops_trampoline
do_for_each_ftrace_op(op, ftrace_ops_list) // OOPS! op may be NULL!

Therefore, when ftrace_startup_enable fails, we need to rollback registration
process and remove ops from ftrace_ops_list. |
In the Linux kernel, the following vulnerability has been resolved:
kasan: avoid sleepable page allocation from atomic context
apply_to_pte_range() enters the lazy MMU mode and then invokes
kasan_populate_vmalloc_pte() callback on each page table walk iteration.
However, the callback can go into sleep when trying to allocate a single
page, e.g. if an architecutre disables preemption on lazy MMU mode enter.
On s390 if make arch_enter_lazy_mmu_mode() -> preempt_enable() and
arch_leave_lazy_mmu_mode() -> preempt_disable(), such crash occurs:

The reason for the warning is clear enough; the driver sends an
unusual read request on endpoint 0 but does not set the USB_DIR_IN bit
in the bRequestType field.
More importantly, the whole situation can be avoided and the driver
simplified by converting it over to the relatively new
usb_control_msg_recv() and usb_control_msg_send() routines. That's
what this fix does. |

The fix is re-ordering the code related to OPP core. The OPP core
expects all configuration options to be provided before the OPP
table is added. |
Chromium Embedded Framework (CEF) is a simple framework for embedding Chromium-based browsers in other applications.`CefVideoConsumerOSR::OnFrameCaptured` does not check `pixel_format` properly, which leads to out-of-bounds read out of the sandbox. This vulnerability was patched in commit 1f55d2e.
