CVE-2024-58053

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.

This vulnerability is rated as Moderate because an unprivileged local user can trigger an indefinite hang on active rxrpc connections, leading to denial of service without compromising data confidentiality or system integrity. Red Hat Enterprise Linux does not load the rxrpc network protocol module by default, confining exposure to environments actively using AF_RXRPC sockets or the in-kernel AFS filesystem. As a result, standard deployments that do not utilize these network protocols remain unaffected under default conditions.
