Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the Linux kernel, specifically in the drm/amdkfd module. It occurs when the write dbg ev file function is executed after debug trap disable, causing a NULL pointer access. This happens because write dbg ev file is run by a work queue in interrupt context. To resolve this, it is recommended to cancel the work "debug event workarea" before setting dbg ev file as NULL.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
