Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992309)

medium Nessus Plugin ID 280565

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-2025-992309 advisory.

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

 ipvs: fix WARNING in __ip_vs_cleanup_batch()

 During the initialization of ip_vs_conn_net_init(), if file ip_vs_conn or ip_vs_conn_sync fails to be created, the initialization is successful by default. Therefore, the ip_vs_conn or ip_vs_conn_sync file doesn't be found during the remove.

 The following is the stack information:
 name 'ip_vs_conn_sync' WARNING: CPU: 3 PID: 9 at fs/proc/generic.c:712 remove_proc_entry+0x389/0x460 Modules linked in:
 Workqueue: netns cleanup_net RIP: 0010:remove_proc_entry+0x389/0x460 Call Trace:

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
