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

Description The issue is related to a null pointer dereference in the Linux kernel's drm/amdgpu/vkms component. Specifically, in the amdgpu vkms conn get modes() function, the return value of drm cvt mode() is assigned to mode, which can lead to a null pointer dereference if drm cvt mode() fails. To address this, a check has been added to avoid the null pointer dereference. The vulnerability can be exploited to cause a denial of service.

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