Subject: [PATCH 0/2] net: ieee802154: fix logic errors
Date: Fri, 23 Apr 2021 00:02:12 -0400 [thread overview]
Message-ID: <20210423040214.15438-1-dan@dlrobertson.com> (raw)
I hit two null derefs due to logic errors.
- ieee802154_llsec_parse_key_id null deref if PAN ID is null.
- ieee802154_llsec_parse_dev_addr null deref if the given mode
does not match the given address.
New to ieee802154, so feedback would definitely be appreciated.
