Linux Kernel Restart Flag Management Vulnerability in DRM/xe/PXP Component

A vulnerability has been addressed in the Linux kernel's DRM/xe/PXP component. The issue arose because a restart flag was not cleared properly, causing the function to loop back to the beginning instead of proceeding as intended. This vulnerability affects the Linux kernel stable tree.

Impact

Failure to clear the restart flag could lead to unintended function behavior, causing the process to restart prematurely, which may disrupt normal operations or processing sequences.

Reproduction

The vulnerability can be reproduced by invoking the PXP start function in the DRM/xe driver without the restart flag being cleared. This will cause the function to incorrectly loop back to the start after reaching the end, instead of completing the process as intended.

Remediation

Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
