CVE-2026-53379: media: i2c: ov8856: free control handler on error in ov8856_init_controls()

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: 0.16% (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 791598484fd558bb426ef5e051effa5c227d5390, ba9e9274c4ecfc039c45752dd6055137eaa5f08e, c13721040a566d832ee8a20ecf04b7ef288a1525.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 791598484fd558bb426ef5e051effa5c227d5390, ba9e9274c4ecfc039c45752dd6055137eaa5f08e, c13721040a566d832ee8a20ecf04b7ef288a1525 or later.
