What to do

AI-suggested

A fix has been implemented in the Linux kernel to explicitly flush exception handling work during suspend when RPM level is zero. Users should apply the updated kernel version containing this patch to prevent system crashes related to this issue.

Description

A vulnerability in the Linux kernel's UFS core driver related to flush exception handling during runtime power management has been resolved. The issue involved a race condition where exception handling work was not flushed when the runtime power management (RPM) level was zero, potentially causing system crashes during suspend. The fix ensures that exception event handling work is explicitly flushed during suspend when RPM level is UFS_PM_LVL_0, preventing illegal hardware access during power-down.
