CVE-2024-40973: media: mtk-vcodec: potential null pointer deference in SCP
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: 0.29% (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 19ef02106c990bf4235365a08b9d8d2fee37272a, 3a693c7e243b932faee5c1fb728efa73f0abc39b, 53dbe08504442dc7ba4865c09b3bbf5fe849681b.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Linux Linux 19ef02106c990bf4235365a08b9d8d2fee37272a, 3a693c7e243b932faee5c1fb728efa73f0abc39b, 53dbe08504442dc7ba4865c09b3bbf5fe849681b or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: media: mtk-vcodec: potential null pointer deference in SCP The return value of devm_kzalloc() needs to be checked to avoid NULL pointer deference. This is similar to CVE-2022-3113.

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.
