CVE-2023-3674
CWE-1283Published: July 19, 2023· Updated: Jun 17, 2026
2.8
CVSS v3.1
Official Description
A flaw was found in the keylime attestation verifier, which fails to flag a device's submitted TPM quote as faulty when the quote's signature does not validate for some reason. Instead, it will only emit an error in the log without flagging the device as untrusted.
Technical Analysis
CVE-2023-3674 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
