kernel: ipv4: validate checksum_start before completing checksum

A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during...

SUSE CVE-2026-105483

A flaw in Node.js TLS hostname verification allows a certificate without a matching IP address SAN to authenticate a connection to an IPv4 address when the host is written with non-ASCII characters, such as fullwidth digits １２７.0.0.1. tls.checkServerIdentity did not recognize such hosts as IP...

kernel: ipv4: raw: reject IP_HDRINCL packets with ihl < 5

A flaw was found in the Linux kernel's handling of IPv4 raw sockets. An unprivileged attacker with CAPNETRAW capabilities can craft and inject a malformed IPv4 packet with an invalid Internet Header Length IHL. This can lead to an out-of-bounds memory access when the packet is processed by certai...
