CVE-2026-45850

CVE-2026-45850 relates to the Linux kernel’s IPVS handling of IPv6: protocol checksum validation can fail when IPv6 extension headers precede the protocol header. The fix uses iph->len as the offset rather than the previous value, addressing the miscalc that allowed incorrect checksums. Affect...

kernel: net: incorrect processing of checksums in UDP implementation

A flaw was found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in...
