CVE-2022-50420: crypto: hisilicon/hpre - fix resource leak in remove process

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: 0.15% (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 2b3e3ecdb402ff1053ee25b598ff21b9ddf4384f, 45e6319bd5f2154d8b8c9f1eaa4ac030ba0d330c, 4e0de941d252d4e7c985981e78480c8d6f020b64.

Low priority for now. Upgrade to Linux Linux 2b3e3ecdb402ff1053ee25b598ff21b9ddf4384f, 45e6319bd5f2154d8b8c9f1eaa4ac030ba0d330c, 4e0de941d252d4e7c985981e78480c8d6f020b64 or later.
