CVE-2024-42101

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: fix null pointer dereference in nouveau_connector_get_modes

In nouveau_connector_get_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

Weakness

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.
