CVE-2026-0826 is a critical unauthenticated stack-based buffer overflow affecting HP Poly Voice/VoIP devices on the Linux platform, including Poly VVX and Trio product lines. The flaw is exposed when Interactive Connectivity Establishment (ICE) is enabled. According to the provided content, the vulnerable code resides in SDP parsing of ICE candidate attributes within the polyapp binary, specifically in the ParseICECandidate helper reached from ParseRemoteSDP and IceSession::ParseRemoteSdpForAddresses. Attacker-controlled candidate data is copied into a 256-byte stack buffer via memcpy without proper length validation, allowing an oversized SDP candidate attribute delivered in a crafted SIP INVITE request to overflow the stack and overwrite control data such as the program counter. Rapid7 reported and demonstrated exploitation against firmware 6.4.7.4477, and public technical details and exploit code, including a Metasploit module, have been released.
