Last modified
CVE-2021-3600 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code.. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
