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

Description The Linux kernel contains a flaw within the DRM client modeset probe function. Specifically, the modes variable in drm client modeset probe may fail to allocate memory using kcalloc. If this occurs, the code attempts to destroy the uninitialized modes variable, leading to a potential NULL pointer dereference. This can occur in error scenarios.

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