CVE-2024-27072: media: usbtv: Remove useless locks in usbtv_video_free()

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 3e7d82ebb86e94643bdb30b0b5b077ed27dce1c2, 4ec4641df57cbdfdc51bb4959afcdbcf5003ddb9, 65e6a2773d655172143cc0b927cdc89549842895.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 3e7d82ebb86e94643bdb30b0b5b077ed27dce1c2, 4ec4641df57cbdfdc51bb4959afcdbcf5003ddb9, 65e6a2773d655172143cc0b927cdc89549842895 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: media: usbtv: Remove useless locks in usbtv_video_free() Remove locks calls in usbtv_video_free() because are useless and may led to a deadlock as reported here: https://syzkaller.appspot.com/x/bisect.txt?x=166dc872180000 Also remove usbtv_stop() call since it will be called when unregistering the device. Before 'c838530d230b' this issue would only be noticed if you disconnect while streaming and now it is noticeable even when disconnecting while not streaming.

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.
