CVE-2025-45331Network attack vector

Unauthenticated service crash via null data dereference

Published Jun 20, 2025 · Updated Jun 24, 2025

Null pointer dereference in brplot 420.69.1 allows remote attackers to crash the application through network-reachable data processing. The br_dagens_handle_once function marks a generator as failed when br_data_get1 returns NULL, then passes d->group_id to br_data_clear without checking d. No authentication or user interaction is required; exploitation terminates the plotting process without reported data disclosure or modification.
