Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue arises when the crtc's connectors changed is set without enable/active getting toggled, resulting in an atomic enable() call followed by an atomic disable() but without an atomic mode set(). This leads to a NULL pointer access for the dpu encoder get drm fmt() call in the atomic enable() as the dpu encoder's connector was cleared in the atomic disable() but not re-assigned due to the lack of an atomic mode set() call. The fix involves moving the assignment for atomic enable() and using drm atomic get new connector for encoder() to get the connector from the atomic state.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
