Description

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix handling of received connection abort Fix the handling of a connection abort that we've received. Though the abort is at the connection level, it needs propagating to the calls on that connection. Whilst the propagation bit is performed, the calls aren't then woken up to go and process their termination, and as no further input is forthcoming, they just hang. Also add some tracing for the logging of connection aborts.

How to fix

Upgrade to a fixed version: Linux kernel 6.12.13, 6.13.2, 6.6.76. Check the vendor advisory for mitigations.
