Network Address Translation Vulnerability in Linux Kernel

CVE-2026-100070

What is CVE-2026-100070?

A vulnerability in the Linux kernel's netfilter component could lead to incomplete processing of SIP packets during Network Address Translation. When the NAT process alters packet size, an offset misalignment may occur, potentially causing certain Contact headers to be skipped. This could result in the leakage of internal network details without detection, exposing sensitive information and increasing the risk of network exploitation.
