From 1d0688421449718c6c5f46e458a378c9b530ba18 Mon Sep 17 00:00:00 2001 From: Soenke Huster Date: Wed, 20 Oct 2021 10:14:44 +0200 Subject: [PATCH] Bluetooth: virtio_bt: fix memory leak in virtbt_rx_handle() On the reception of packets with an invalid packet type, the memory of the allocated socket buffers is never freed. Add a default case that frees these to avoid a memory leak.
