CVE-2024-26784: pmdomain: arm: Fix NULL dereference on scmi_perf_domain 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: 0.19% (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 eb5555d422d0fc325e1574a7353d3c616f82d8b5, f6aaf131e4d4a9a26040ecc018eb70ab8b3d355d.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux eb5555d422d0fc325e1574a7353d3c616f82d8b5, f6aaf131e4d4a9a26040ecc018eb70ab8b3d355d or later.

In the Linux kernel, the following vulnerability has been resolved: pmdomain: arm: Fix NULL dereference on scmi_perf_domain removal On unloading of the scmi_perf_domain module got the below splat, when in the DT provided to the system under test the '#power-domain-cells' property was missing. Indeed, this particular setup causes the probe to bail out early without giving any error, which leads to the ->remove() callback gets to run too, but without all the expected initialized structures in place. Add a check and bail out early on remove too.

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.

No history yet (it accumulates with the daily EPSS job).

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 commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

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.
