HP Polycom: CVE-2026-0826: UC Software Stack-Based Buffer Overflow Vulnerability

A critical unauthenticated stack-based buffer overflow vulnerability exists within the core session-handling binary (polyapp) of HP Poly UC Software. The flaw allows a remote, unauthenticated attacker to overflow an internal memory stack buffer by transmitting a specially crafted packet to the device over the network. Successful exploitation grants the attacker full arbitrary code execution with root administrative privileges on the underlying operating system pipeline of the physical asset.
