CVE-2026-97984

The Linux kernel contains a vulnerability where UDP sockets can experience a UDP length overflow when using IPV6_PMTUDISC_DO or IPV6_PMTUDISC_PROBE options. This occurs when sending a large packet over a network device with an unusually large MTU (greater than IP6_MAX_MTU), causing the 16-bit len...
