There is a flaw reported in the Linux kernel in versions before 5.9 in drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker with a local account with a root privilege, can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. Se presenta un fallo reportado en el kernel de Linux en versiones anteriores a 5.9, en el archivo drivers/gpu/drm/nouveau/nouveau_sgdma.c en la función nouveau_sgdma_create_ttm en el subsistema Nouveau DRM. El problema es debido a una falta de comprobación de la existencia de un objeto antes de llevar a cabo operaciones en el objeto. • https://bugzilla.redhat.com/show_bug.cgi?id=1939686 https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html • CWE-416: Use After Free •
