CVE-2026-72374
What it is
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
