CVE-2026-8232Public exploit

UPF process crash via duplicate PDR accumulation

Published May 10, 2026 · Updated May 10, 2026

Denial of service in Dotouch XproUPF 2.0.0-release-088aa7c4 allows remote authenticated users to crash the UPF process via PFCP requests. Repeated PDR-related PFCP operations for one session accumulate duplicate PDR entries instead of replacing or deleting them, until vlib_worker_loop in libvlib.so aborts. The attacker must reach the adjacent PFCP control-plane interface with low privileges; the demonstrated consequence is a UPF process crash with no reported confidentiality or integrity impact.
