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

Fix callback service message parsers to pass through -EAGAIN (NVD)

Monitor Linux's web page for any future patch releases.
