CVE-2022-49952: misc: fastrpc: fix memory corruption on probe
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 0e33b0f322fecd7a92d9dc186535cdf97940a856, 9baa1415d9abdd1e08362ea2dcfadfacee8690b5, c0425c2facd9166fa083f90c9f3187ace0c7837a.
Low priority for now. Upgrade to Linux Linux 0e33b0f322fecd7a92d9dc186535cdf97940a856, 9baa1415d9abdd1e08362ea2dcfadfacee8690b5, c0425c2facd9166fa083f90c9f3187ace0c7837a or later.
