Subject: Re: [PATCH 1/5] ath9k: Fix use-after-free Read in htc_connect_service
Date: Tue, 7 Apr 2020 13:51:55 +0300
Message-ID: <20200407105154.GI2001@kadam> (raw)

This patch is correct but there are a lot of error paths in
hif_usb_send() which don't free the skb.  Some error paths *do* free
the skb but most don't.  It's really a lot of work to sort through and
fix.

regards,
dan carpenter
