Subject: [PATCH wpan 00/17] ieee802154: syzbot fixes
Date: Sun, 28 Feb 2021 10:18:00 -0500
Message-ID: <20210228151817.95700-1-aahringo@redhat.com> (raw)

Hi,

this patch series contains fixes found by syzbot for nl802154 and a
memory leak each time we receiving a skb for monitor interfaces.

The first three patches are misc fixes, all others are to forbid monitor
interfaces to access security mib values which are never initialized for
monitor interfaces yet. We never supported such handling but I can
imagine that we can use security mib for monitor interfaces to decrypt
802.15.4 frames by the Linux kernel and the RAW sockets can see
plaintext then. However it's a possibility for an new feature to check in
due courses.

- Alex
