CVE-2026-74592
Description
A flaw was found in the Linux kernel's Integrity Measurement Architecture (IMA). When a file is truncated, the system's integrity policy hooks are not properly instantiated, preventing the action cache flags from being reset. This oversight means that after truncation, the file is not re-collected, re-measured, re-audited, and re-appraised on subsequent access, potentially allowing an attacker to bypass integrity checks.
