Critical Linux TCP vulnerability CVE-2026-98432 allows remote code execution · 1 source tracked

By PulseAugur Editorial · [1 sources] ·

A critical use-after-free vulnerability, CVE-2026-98432, has been identified in the Linux kernel's IPv4 TCP handshake process. This flaw arises when multiple processors attempt to access the same IP options object concurrently, leading to a situation where one processor frees the object while another, protected by RCU, continues to use it. This can result in a stale kernel pointer, potentially allowing for remote code execution under specific configurations, as demonstrated by Anthropic's Frontier Red Team. AI
