In the Linux kernel, the following vulnerability has been resolved:

afs: Fix callback service message parsers to pass through -EAGAIN

The AFS filesystem client uses an rxrpc server to listen for callback
notifications.  Each callback call type handler has a delivery function
that parses the incoming request stream, and this should return -EAGAIN the
last packet hasn't yet been seen, but all currently queued received data is
consumed.  afs_extract_data() does this, but the -EAGAIN return is switched
to 0 inadvertantly
