About this tag
The Linux IMA (Integrity Measurement Architecture) tag covers discussions about the Linux kernel's integrity measurement subsystem, which records file hashes and can anchor measurements to a TPM for attestation. Recent content highlights CVE-2025-68740, a logic error in IMA rule matching that causes false rule matches when LSM rule objects become NULL, potentially leading to extra file measurements and confusing attestation or appraisal workflows. This tag is relevant for WindowsForum.com users interested in Linux security, kernel vulnerabilities, and integrity measurement, particularly in enterprise or mixed-OS environments where attestation and secure boot are concerns.
