Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the DRM/AMD display subsystem. Specifically, the
dc->links[MAX LINKS] array size was insufficient, leading to potential issues. Additionally, the hw init() function could access a null pointer (LINK ENC) for DPIA non-display endpoints. This issue was addressed by increasing the array size and correcting the null pointer access.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
