Subject: net: atm: Spectre v1 fix introduced bug in bcb964012d1b in -stable
Date: Mon, 20 May 2019 14:40:14 +0200 [thread overview]
Message-ID: <20190520124014.GA5205@amd> (raw)
[-- Attachment #1: Type: text/plain, Size: 714 bytes --]
In lecd_attach, if arg is < 0, it was treated as 0. Spectre v1 fix
changed that. Bug does not exist in mainline AFAICT.
