In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Fix warnings during S3 suspend
The enable_gpe_wakeup() function calls acpi_enable_all_wakeup_gpes(),
and the later one may call the preempt_schedule_common() function,
resulting in a thread switch and causing the CPU to be in an interrupt
enabled state after the enable_gpe_wakeup() function returns, leading
to the warnings as follow.

The root cause is acpi_enable_all_wakeup_gpes() uses a mutex to protect
acpi_hw_enable_all_wakeup_gpes(), and acpi_ut_acquire_mutex() may cause
a thread switch. Since there is no longer concurrent execution during
loongarch_acpi_suspend(), we can call acpi_hw_enable_all_wakeup_gpes()
directly in enable_gpe_wakeup().
The solution is similar to commit 22db06337f590d01 ("ACPI: sleep: Avoid
breaking S3 wakeup due to might_sleep()").

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
