CVE-2024-42313: media: venus: fix use after free in vdec_close

Noroxi assessment

Priority: Monitor (action score 31/100)

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: 0.23% (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 4c9d235630d35db762b85a4149bbb0be9d504c36, 66fa52edd32cdbb675f0803b3c4da10ea19b6635, 6a96041659e834dc0b172dda4b2df512d63920c2; Azure Linux 3.0 ARM 6.6.47.1-1; Azure Linux 3.0 x64 6.6.47.1-1.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 4c9d235630d35db762b85a4149bbb0be9d504c36, 66fa52edd32cdbb675f0803b3c4da10ea19b6635, 6a96041659e834dc0b172dda4b2df512d63920c2; Azure Linux 3.0 ARM 6.6.47.1-1; Azure Linux 3.0 x64 6.6.47.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: media: venus: fix use after free in vdec_close There appears to be a possible use after free with vdec_close(). The firmware will add buffer release work to the work queue through HFI callbacks as a normal part of decoding. Randomly closing the decoder device from userspace during normal decoding can incur a read after free for inst. Fix it by cancelling the work in vdec_close.

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.

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.
