CVE-2025-22095: PCI: brcmstb: Fix error path after a call to regulator_bulk_get()

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 3651ad5249c51cf7eee078e12612557040a6bdb4, 6f44e1fdb006db61394aa4d4c25728ada00842e7, 7842e842a9bf6bd5866c84f588353711d131ab1a.

Low priority for now. Upgrade to Linux Linux 3651ad5249c51cf7eee078e12612557040a6bdb4, 6f44e1fdb006db61394aa4d4c25728ada00842e7, 7842e842a9bf6bd5866c84f588353711d131ab1a or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: PCI: brcmstb: Fix error path after a call to regulator_bulk_get() If the regulator_bulk_get() returns an error and no regulators are created, we need to set their number to zero. If we don't do this and the PCIe link up fails, a call to the regulator_bulk_free() will result in a kernel panic. While at it, print the error value, as we cannot return an error upwards as the kernel will WARN() on an error from add_bus().

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.
