Priority: Monitor (action score 0/100)

  • 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).
  • Fixed version: Linux Linux 02a24f13b3a1d9da9f3de56aa5fdb7cc1fe167a2, c9e024e907cafafd6b094f69a0d0f5d18fd28876, ec2f87ad035e8d1ad67567542842f1f23a4dbde2.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: media: iris: Fix memory leak by freeing untracked persist buffer One internal buffer which is allocated only once per session was not being freed during session close because it was not being tracked as part of internal buffer list which resulted in a memory leak. Add the necessary logic to explicitly free the untracked internal buffer during session close to ensure all allocated memory is released properly.
