Subject: [PATCH] net/bnxt: fix memory corruption in tunnel entry list
Date: Mon, 5 Oct 2026 15:25:47 -0500 [thread overview]
Message-ID: <20261005202547.18322-1-manish.kurup@broadcom.com> (raw)
From: Kishore Padmanabha <kishore.padmanabha@broadcom.com>
When the app tunnel table is full, ref_cnt is never zero, so
free_entry ends up as -1 and the wrong tunnel slot gets updated.
Use the correct index instead of free_entry.
Fixes: bdf4a3c6316b ("net/bnxt: support tunnel offload")
