Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.37

Description The issue is related to a callback function pointer check in the Linux kernel's drm/msm/dpu module. Specifically, in the dpu core irq callback handler() function, the callback function pointer is compared to NULL but then unconditionally called by this pointer. This bug has been fixed by adding a conditional return. The Linux Verification Center (linuxtesting.org) found this issue using SVACE.

Recommendations Update to Linux kernel version 6.6.37 or later to resolve the issue. As a temporary workaround, consider adding a conditional check for the callback function pointer before calling it to prevent potential crashes or exploits.
