Technical description

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

afs: Fix the setting of the server responding flag

In afs_wait_for_operation(), we set transcribe the call responded flag to

the server record that we used after doing the fileserver iteration loop -

but it's possible to exit the loop having had a response from the server

that we've discarded (e.g. it returned an abort or we started receiving

data, but the call didn't complete).

This means that op->server might be NULL, but we don't check that before

attempting to set the server flag.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
