CVE-2022-48661: gpio: mockup: Fix potential resource leakage when register a chip

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: 0.22% (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 02743c4091ccfb246f5cdbbe3f44b152d5d12933, 41f857033c44442a27f591fda8d986e7c9e42872, 9b26723e058faaf11b532fb4aa16d6849d581790.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 02743c4091ccfb246f5cdbbe3f44b152d5d12933, 41f857033c44442a27f591fda8d986e7c9e42872, 9b26723e058faaf11b532fb4aa16d6849d581790 or later.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
