CVE-2024-38627: stm class: Fix a double free in stm_register_device()

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: 0.25% (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 370c480410f60b90ba3e96abe73ead21ec827b20, 3df463865ba42b8f88a590326f4c9ea17a1ce459, 4.5.

Low priority for now. Upgrade to Linux Linux 370c480410f60b90ba3e96abe73ead21ec827b20, 3df463865ba42b8f88a590326f4c9ea17a1ce459, 4.5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: stm class: Fix a double free in stm_register_device() The put_device(&stm->dev) call will trigger stm_device_release() which frees "stm" so the vfree(stm) on the next line is a double free.
