Unity Linux 20.1070e Security Update: kernel (UTSA-2025-990789)

medium Nessus Plugin ID 275029

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-2025-990789 advisory.

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

 bpf, sockmap: Fix the sk->sk_forward_alloc warning of sk_stream_kill_queues

 When running `test_sockmap` selftests, the following warning appears:

 WARNING: CPU: 2 PID: 197 at net/core/stream.c:205 sk_stream_kill_queues+0xd3/0xf0 Call Trace:
 <TASK> inet_csk_destroy_sock+0x55/0x110 tcp_rcv_state_process+0xd28/0x1380 ? tcp_v4_do_rcv+0x77/0x2c0 tcp_v4_do_rcv+0x77/0x2c0

 The root case is in commit 84472b436e76 (bpf, sockmap: Fix more uncharged while msg has more_data), where I used msg->sg.size to replace the tosend, causing breakage:

 if (msg->apply_bytes && msg->apply_bytes < tosend) tosend = psock->apply_bytes;

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.
