CVE-2022-0001: Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potential
Noroxi assessment
Priority: Monitor (action score 26/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.50% (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: linux (Debian:11) 5.10.103-1; linux (Debian:12) 5.16.12-1; linux (Debian:9) 4.9.303-1.
- Mentioned 5 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to linux (Debian:11) 5.10.103-1; linux (Debian:12) 5.16.12-1; linux (Debian:9) 4.9.303-1 or later.

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.
