Subject: [PATCH v2 0/2] media: dvb-usb: Fix UAF and memory leaks
Date: Mon,  1 Feb 2021 09:32:45 +0100	[thread overview]
Message-ID: <20210201083247.10760-1-tiwai@suse.de> (raw)

Hi,

here is a revised patch set to address the use-after-free at
disconnecting a USB DVB device that was recently reported on openSUSE
Bugzilla.  The bug itself seems to be a long-standing one, and I
spotted another memory leak there, which is covered in the first
patch.

This revision addressed the double-free bug Sean pointed.

I added Robert's R-b tag only to patch#2, as patch#1 differs from the
v1 significantly.


thanks,

Takashi
