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

Description A flaw exists in the Linux kernel’s drm/msm/dpu subsystem. Specifically, a missing check for a null pointer after a kzalloc call can lead to a null pointer dereference within the drm atomic helper crtc reset function. This occurs when kzalloc fails to allocate memory and returns a NULL pointer, and the code proceeds without validating the pointer before using it.

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