Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-388590)

medium Nessus Plugin ID 266831

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-388590 advisory.

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

 sunrpc: clear XPRT_SOCK_UPD_TIMEOUT when reset transport

 Since transport->sock has been set to NULL during reset transport, XPRT_SOCK_UPD_TIMEOUT also needs to be cleared. Otherwise, the xs_tcp_set_socket_timeouts() may be triggered in xs_tcp_send_request() to dereference the transport->sock that has been set to NULL.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
