CVE-2026-0794Network attack vector

Unauthenticated code execution via SIP use-after-free

Published Jan 23, 2026 · Updated Jan 23, 2026

Use-after-free in Algo 8180 IP Audio Alerter 5.5 SIP call handling allows remote attackers to execute arbitrary code. The SIP call handler operates on an object without first confirming that the object still exists, leaving freed memory accessible. No authentication or user interaction is required, but exploitation has high complexity and runs code only in the device context.
