Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.1.0-rc1+ #364
Description
The Linux kernel contains a flaw related to a potential null pointer dereference within the Direct Rendering Manager (DRM) subsystem. Specifically, the
drmm mode config init() function calls drm mode create standard properties() without checking its return value. If drm mode create standard properties() fails due to memory allocation, the property pointer can become NULL, leading to a null pointer dereference. This condition was observed during testing with the bochs module, resulting in a general protection fault. The vulnerable code path involves the drm object attach property() function.Recommendations
Update to Linux kernel version 6.1.0-rc1+ #364 or a later version to resolve this issue.
