CVE-2023-52918: media: pci: cx23885: check cx23885_vdev_init() return

MediumCVSS 5.5 · v3.1—No exploit Fix available

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: 0.20% (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 06ee04a907d64ee3910fecedd05d7f1be4b1b70e, 15126b916e39b0cb67026b0af3c014bfeb1f76b3, 199a42fc4c45e8b7f19efeb15dbc36889a599ac2.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 06ee04a907d64ee3910fecedd05d7f1be4b1b70e, 15126b916e39b0cb67026b0af3c014bfeb1f76b3, 199a42fc4c45e8b7f19efeb15dbc36889a599ac2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: media: pci: cx23885: check cx23885_vdev_init() return cx23885_vdev_init() can return a NULL pointer, but that pointer is used in the next line without a check. Add a NULL pointer check and go to the error unwind if it is NULL.
