CVE-2022-50319: coresight: trbe: remove cpuhp instance node before remove cpuhp state
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: 0.15% (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 18b9202188a4e59923834c60b5c82ea1da7d1811, 20ee8c223f792947378196307d8e707c9cdc2d61, 2ea334960afcd49385840c7afd59fc5f8d3ce682.
Low priority for now. Upgrade to Linux Linux 18b9202188a4e59923834c60b5c82ea1da7d1811, 20ee8c223f792947378196307d8e707c9cdc2d61, 2ea334960afcd49385840c7afd59fc5f8d3ce682 or later.

In the Linux kernel, the following vulnerability has been resolved: coresight: trbe: remove cpuhp instance node before remove cpuhp state cpuhp_state_add_instance() and cpuhp_state_remove_instance() should be used in pairs. Or there will lead to the warn on cpuhp_remove_multi_state() since the cpuhp_step list is not empty. The following is the error log with 'rmmod coresight-trbe': Error: Removing state 215 which has instances left.

Exploit status
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.
Research context
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.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

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.
