# CVE-2026-72096: dm-verity: make error counter atomic

Status: published. Published: 2026-08-15. Updated: 2026-11-06.

In the Linux kernel, the following vulnerability has been resolved:

dm-verity: make error counter atomic

The error counter "v->corrupted_errs" was not atomic, thus it could be
subject to race conditions. The call to
dm_audit_log_target("max-corrupted-errors") may be skipped due to the
races.
