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

Description A flaw exists in the Linux kernel’s drm/i915 component related to handling encoder retrieval within the atomic state. Specifically, the intel get crtc new encoder() function could lead to a system crash if a connector for the CRTC was not found in the atomic state. The issue was addressed by obtaining the device pointer from the atomic state instead of a potentially null encoder, preventing the crash.

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