CVE-2020-10751 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message.

EPSS estimates a 0.35% chance of exploitation in the next 30 days.
