Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-401595)

medium Nessus Plugin ID 267342

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-2025-401595 advisory.

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

 eth: sungem: remove .ndo_poll_controller to avoid deadlocks

 Erhard reports netpoll warnings from sungem:

 netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (gem_start_xmit+0x0/0x398) WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c

 gem_poll_controller() disables interrupts, which may sleep.
 We can't sleep in netpoll, it has interrupts disabled completely.
 Strangely, gem_poll_controller() doesn't even poll the completions, and instead acts as if an interrupt has fired so it just schedules NAPI and exits. None of this has been necessary for years, since netpoll invokes NAPI directly.

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.
