Technical description

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

rxrpc: Fix the reception of a reply packet before data transmission

Fix rxrpc_receiving_reply() to handle the reception of an apparent reply

DATA packet before rxrpc has had a chance to send any request DATA packets

on a client call by checking to see if the call has been exposed yet by

sending the first packet.

Without this, rxrpc_rotate_tx_window() might oops.

Also fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by

changing the do...while loop into a while loop, just in case a call is

abnormally terminated by an early reply before the last request packet is

transmitted.

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.
