Last modified
CVE-2023-52340 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The IPv6 implementation in the Linux kernel before 6.3 has a net/ipv6/route.c max_size threshold that can be consumed easily, e.g., leading to a denial of service (network is unreachable errors) when IPv6 packets are sent in a loop via a raw socket.. EPSS estimates a 0.94% chance of exploitation in the next 30 days.
