About this tag
CVE-2025-68740 is a Linux kernel vulnerability affecting the Integrity Measurement Architecture (IMA). It involves a logic error where LSM rule objects can become NULL, causing false rule matches. This leads IMA to measure extra files, potentially disrupting attestation and appraisal workflows. The tag covers discussions about the bug's impact on Linux security, including how it can confuse integrity measurements and TPM-anchored attestation. Patches are needed to correct the rule-matching logic. This tag is relevant for Linux system administrators, security researchers, and enterprise IT professionals managing kernel security and integrity verification.
