keylime: A flaw was found in Keylime
CVE-2026-6420 is fixed in 8 products on 1 platform, first by RHSA-2026:28582, released May 6, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in Keylime. An attacker with root access on an enrolled monitored machine, where the Keylime agent runs, can exploit a vulnerability in the Keylime verifier. The verifier uses a hardcoded challenge nonce for Trusted Platform Module (TPM) quote attestation instead of a cryptographically random value. This allows the attacker to stockpile valid TPM quotes and replay them to evade detection after compromising the system. This issue affects only the push model deployment.
