ASoC: samsung: Fix refcount leak in aries_audio_probe

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: 0.26% (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 46d1b310a2d571811c4e08041ce287babb60b86a, 70130bde3457d28c02c76b6cacc5d40a72dd6e17, 85d899f396622d3034643bf89615a78f9be7c91a.

Low priority for now. Upgrade to Linux Linux 46d1b310a2d571811c4e08041ce287babb60b86a, 70130bde3457d28c02c76b6cacc5d40a72dd6e17, 85d899f396622d3034643bf89615a78f9be7c91a or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ASoC: samsung: Fix refcount leak in aries_audio_probe of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. If extcon_find_edev_by_node() fails, it doesn't call of_node_put() Calling of_node_put() after extcon_find_edev_by_node() to fix this.

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.

EPSS, last 120 days

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.

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.
