Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987034)

high Nessus Plugin ID 267995

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-2025-987034 advisory.

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

 usb: gadget: rndis: add spinlock for rndis response list

 There's no lock for rndis response list. It could cause list corruption if there're two different list_add at the same time like below.
 It's better to add in rndis_add_response / rndis_free_response / rndis_get_next_response to prevent any race condition on response list.

 [ 361.894299] [1: irq/191-dwc3:16979] list_add corruption.
 next->prev should be prev (ffffff80651764d0), but was ffffff883dc36f80. (next=ffffff80651764d0).
