Memory leak in Linux kernel - CVE-2022-49829

Vulnerability identifier: #VU108178

CSH Severity: Low

CVSS v4 BT: 4.3 [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/E:U/U:Clear]

CVE-ID: CVE-2022-49829

CWE-ID: CWE-401

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 memory leak within the drm_sched_entity_kill_jobs_cb() and drm_sched_entity_kill_jobs() functions in drivers/gpu/drm/scheduler/sched_entity.c. A local user can perform a denial of service (DoS) attack.
