Subject: [PATCH net v3 0/1] atm: mpoa: Fix UAF on qos_head list in procfs
Date: Thu, 4 Dec 2025 15:24:20 +0900 [thread overview]
Message-ID: <20251204062421.96986-1-ii4gsp@gmail.com> (raw)
Changes since v2:
- Replace atm_mpoa_search_qos() with atm_mpoa_get_qos() to avoid
returning an unprotected pointer.
- Add atm_mpoa_delete_qos_by_ip() so search+unlink+free is atomic
under qos_mutex, preventing double-free/UAF.
- Update all callers accordingly.
