The vulnerabilities of the functions nv50_piorDestroy() and nv50_piorCreate() in the driver/gpu/drm/nouveau/dispnv50/disp.c file of the Nouveau driver for the Direct Rendering Infrastructure (DRI) of NVIDIA’s Linux kernel allow a malicious actor to cause a service failure.

The vulnerability of the functions nv50piordestroy and nv50piorcreate in the drivers/gpu/drm/nouveau/dispnv50/disp.c module of the Nouveau graphics driver for Linux operating systems is related to the lack of resource initialization. Exploiting this vulnerability can allow an attacker to cause a...
