The ip_push_pending_frames function in Linux 2.4.x and 2.6.x before 2.6.16 increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows remote attackers to conduct an Idle Scan (nmap -sI) attack, which bypasses intended protections against such attacks.

Security readout for executives and security teams

This old Linux kernel flaw can let a remote attacker use an affected host as a “blind probe” to infer whether other systems or ports are reachable. It does not directly grant code execution or data access, but it can weaken network reconnaissance controls and hide the attacker's real scanning source. Exposure is mainly legacy Linux systems still running 2.4.x or 2.6.x kernels before 2.6.16, including embedded or unsupported appliances. Internet-facing hosts are more relevant because they can be abused for reconnaissance. Medium priority for normal enterprises, higher where legacy internet-facing Linux systems remain. The business risk is stealthier reconnaissance and weakened perimeter visibility, not immediate takeover. Mitigation focus: Upgrade affected Linux kernels to a vendor-fixed or supported release.; Review Red Hat, Ubuntu, Debian, SUSE, or appliance vendor advisories for backported fixes.; Prioritize internet-facing legacy Linux hosts and embedded systems..
