usb: typec: tcpm: Fix NULL pointer dereference in tcpm_pd_svdm()
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 4987daf86c152ff882d51572d154ad12e4ff3a4b, 9ee038590d808a95d16adf92818dcd4752273c08, b37a168c0137156042a0ca9626651b5a789e822b.
Low priority for now. Upgrade to Linux Linux 4987daf86c152ff882d51572d154ad12e4ff3a4b, 9ee038590d808a95d16adf92818dcd4752273c08, b37a168c0137156042a0ca9626651b5a789e822b or later.
