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

Description A flaw exists in the Linux kernel’s amdgpu display driver where a null pointer dereference could occur. Specifically, the adev->dm.dc pointer could be NULL and subsequently dereferenced within the amdgpu dm fini() function without a prior check. This issue was discovered by the Linux Verification Center (linuxtesting.org) using SVACE. The fix involves adding a NULL pointer check before calling the dc dmub srv destroy() function.

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