CVE-2020-8694: Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an authenticated user to potentially enable in

Noroxi assessment

Priority: Monitor (action score 22/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.45% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: intel-ucode (Alpine:v3.13) 20201110-r0, 20201112-r0; linux (Debian:12) 5.9.9-1; linux (Debian:9) 4.9.246-1.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to intel-ucode (Alpine:v3.13) 20201110-r0, 20201112-r0; linux (Debian:12) 5.9.9-1; linux (Debian:9) 4.9.246-1 or later.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
