Detailsinfo

A vulnerability has been found in Linux Kernel up to 5.15.196/6.1.158/6.6.116/6.12.57/6.17.7 and classified as critical. Affected by this vulnerability is the function __drm_gem_reset_shadow_plane of the component sysfb. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/sysfb: Do not dereference NULL pointer in plane reset The plane state in __drm_gem_reset_shadow_plane() can be NULL. Do not deref that pointer, but forward NULL to the other plane-reset helpers. Clears plane->state to NULL. v2: - fix typo in commit description (Javier)

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2025-40360 since 04/16/2025. Technical details are known, but no exploit is available.
