CVE-2026-74592Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: ima: Instantiate file_truncate and path_truncate hooks Instantiate the file_truncate and path_truncate LSM hooks to reset the action cache flags (IMA_DONE_MASK) as soon as truncation is requested, so the file, based on policy, is re-collected, re-measured, re-audited, and re-appraised on next access. 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.
