Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved. The issue arises from the enable gpe wakeup() function calling acpi enable all wakeup gpes(), which may lead to a thread switch and cause the CPU to be in an interrupt-enabled state after the enable gpe wakeup() function returns. This results in warnings during S3 suspend. The root cause is the use of a mutex to protect acpi hw enable all wakeup gpes() and the potential for a thread switch caused by acpi ut acquire mutex(). The solution involves calling acpi hw enable all wakeup gpes() directly in enable gpe wakeup() to avoid concurrent execution during loongarch acpi suspend().
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
