Overview

CVE-2024-50294 is a high-severity vulnerability. It was published on November 19, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

Technical description

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

rxrpc: Fix missing locking causing hanging calls

If a call gets aborted (e.g. because kafs saw a signal) between it being

queued for connection and the I/O thread picking up the call, the abort

will be prioritised over the connection and it will be removed from

local->new_client_calls by rxrpc_disconnect_client_call() without a lock

being held. This may cause other calls on the list to disappear if a race

occurs.

Fix this by taking the client_call_lock when removing a call from whatever

list its ->wait_link happens to be on.

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.
