What happened
Rapid7 Labs discovered CVE-2026-0826, a critical unauthenticated stack-based buffer overflow in HP/Poly VoIP phones (VVX series: VVX 150/250/350/450 and three Trio models). The flaw is in parsing Session Description Protocol (SDP) attributes for Interactive Connectivity Establishment (ICE); when ICE is enabled (not enabled by default), a remote unauthenticated attacker can trigger a stack overflow to achieve remote code execution as root. Vendor has released fixes; mitigations include applying vendor patches urgently or disabling the ICE feature until patched.
