CVE-2025-68204: pmdomain: arm: scmi: Fix genpd leak on provider registration failure

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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).
  • Fixed version: Linux Linux 18249a167ffd91b4b4fbd92afd4ddcbf3af81f35, 582f48d22eb5676fe7be3589b986ddd29f7bf4d1, 7458f72cc28f9eb0de811effcb5376d0ec19094a; azl3 kernel 6.6.117.1-1 on Azure Linux 3.0 6.6.119.3-1.

Low priority for now. Upgrade to Linux Linux 18249a167ffd91b4b4fbd92afd4ddcbf3af81f35, 582f48d22eb5676fe7be3589b986ddd29f7bf4d1, 7458f72cc28f9eb0de811effcb5376d0ec19094a; azl3 kernel 6.6.117.1-1 on Azure Linux 3.0 6.6.119.3-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: pmdomain: arm: scmi: Fix genpd leak on provider registration failure If of_genpd_add_provider_onecell() fails during probe, the previously created generic power domains are not removed, leading to a memory leak and potential kernel crash later in genpd_debug_add(). Add proper error handling to unwind the initialized domains before returning from probe to ensure all resources are correctly released on failure.

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.

Bug bounty scope

No known public program.

Technical details

No CVSS vector for this record, so attack conditions can't be derived.
