Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-391543)

medium Nessus Plugin ID 266771

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-2025-391543 advisory.

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

 net: hns3: fix a deadlock problem when config TC during resetting

 When config TC during the reset process, may cause a deadlock, the flow is as below:
 pf reset start ? ? ......
 setup tc ? ? ? ? DOWN: napi_disable() napi_disable()(skip) ? ? ? ? ? ...... ......
 ? ? ? ? napi_enable() ? ? UINIT: netif_napi_del() ? ? ......
 ? ? INIT: netif_napi_add() ? ? ...... global reset start ? ? ? ? UP: napi_enable()(skip) ......
 ? ? ? ? ...... napi_disable()

 In reset process, the driver will DOWN the port and then UINIT, in this case, the setup tc process will UP the port before UINIT, so cause the problem. Adds a DOWN process in UINIT to fix it.

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.
