CVE-2026-74597

A flaw was found in the Linux kernel's IPv6 Internet Protocol version 6 tunnel error handling. A remote attacker could send a specially crafted IPv6 ICMP Internet Control Message Protocol error packet with a malformed inner destination-options header. This could lead to memory corruption within t...

CVE-2026-74669

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When processing Internet Control Message Protocol ICMP errors for tunneled packets, the system can incorrectly use a stale IPv4 option offset. A remote attacker could exploit this by sending a specially crafted ICMP packet,...
