NULL pointer dereference in Linux kernel - CVE-2024-26657

Vulnerability identifier: #VU88146

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2024-26657

CWE-ID: CWE-476

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in drivers/gpu/drm/scheduler/sched_entity.c. A local user can send an amdgpu_cs_wait_ioctl to the AMDGPU DRM driver on any ASICs with valid context and perform a denial of service (DoS) attack.
