CVSS 3.0
4.4 mediumCVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:NCVE-2016-9604
Medium (4.4) in linux linux kernel. EPSS 0.3% chance of exploitation in the next 30 days.
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.
