Affected: freedesktop.org libslirp

An out-of-bounds heap read and integer underflow in the TCP urgent data handling (sosendoob) in freedesktop.org libslirp version before v4.9.2 on hypervisor host environments (e.g., QEMU) allows a privileged guest VM attacker (root or CAP_NET_RAW) to leak gigabytes of sensitive host-process heap memory via sending crafted TCP segments with manipulated URG flags and urgent pointers (ti_urp).

 https://cve.radiocsirt.org/vuln/usn-8550-1 USN-8550-1 — libslirp vulnerability 2026-10-07T22:44:23.755186+00:00

Affected: Ubuntu:22.04:LTS: libslirp, Ubuntu:24.04:LTS: libslirp, Ubuntu:26.04:LTS: libslirp

It was discovered that libslirp incorrectly handled TCP urgent data. A privileged attacker inside a guest VM could possibly use this issue to obtain sensitive information from the host process memory.
