Description

It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.

Faiblesses (CWE)

  • CWE-732 — Attribution de permissions incorrecte sur une ressource critique
  • CWE-347 — Vérification incorrecte d'une signature cryptographique
