Improper locking in Linux kernel - CVE-2025-38703

Vulnerability identifier: #VU114836

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-2025-38703

CWE-ID: CWE-667

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 improper locking within the xe_hw_fence_irq_finish() function in drivers/gpu/drm/xe/xe_hw_fence.c, within the __guc_exec_queue_fini_async() and guc_exec_queue_init() functions in drivers/gpu/drm/xe/xe_guc_submit.c. A local user can perform a denial of service (DoS) attack.
