CVE-2022-49777: Input: i8042 - fix leaking of platform device on module removal
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.21% (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 Linux 3f25add5ecf88de0f8ff2b27b6c0731a1f1b38ed, 4.19.267, 4f348b60c79671eee33c1389efe89109c93047da.
Low priority for now. Upgrade to Linux Linux 3f25add5ecf88de0f8ff2b27b6c0731a1f1b38ed, 4.19.267, 4f348b60c79671eee33c1389efe89109c93047da or later.

No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.

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.
