CVE-2026-9054 Details
Description
An attacker sending tcp, il, rudp, rudp, or gre packets with a length less than the header size would trigger a kernel panic.
A vulnerability in the 9front operating system's networking stack can lead to a kernel panic. This issue occurs when an attacker sends TCP, IL, RUDP, or GRE packets that are shorter than the expected header size. The networking code attempts to process these malformed packets, leading to an assertion failure and a subsequent panic. The vulnerability arises because the packet length is not properly validated before being trimmed, allowing for negative lengths that trigger the kernel panic.
Users can update to the latest version of 9front, where this vulnerability has been addressed. Instructions for updating can be found in the 9front documentation.
