CVE-2023-53833

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

Description The Linux kernel contains a flaw within the DRM/i915 driver where a NULL pointer dereference can occur. Specifically, the intel atomic get new crtc state function may return NULL under certain conditions if a CRTC state was not previously obtained with intel atomic get crtc state. The absence of a NULL check can lead to a dereference of a NULL pointer. This issue was addressed by adding a NULL check to ensure the pointer is valid before use, similar to existing checks in other parts of the code.

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