Race condition in Linux kernel - CVE-2025-10263

Vulnerability identifier: #VU136964

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-362

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 synchronization in broadcast TLB invalidation completion handling in the arm64 TLB invalidation logic when performing memory accesses translated by an invalidated TLB entry after a TLBI;DSB sequence. A local user can trigger affected memory access patterns to cause a denial of service.

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