Improper locking in Linux kernel - CVE-2025-10263

Vulnerability identifier: #VU136690

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-2025-10263

CWE-ID: CWE-667

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper memory synchronization in broadcast TLB invalidation completion handling in the arm64 CPU errata logic when performing broadcast TLB invalidation on affected Arm CPUs. A local user can trigger memory access patterns that rely on invalidated TLB entries to cause a denial of service.

The issue affects only completion of memory accesses translated by an invalidated TLB entry and does not prevent the actual invalidation of TLB entries.
