Unity Linux 20.1070a Security Update: kernel (UTSA-2025-423643)

high Nessus Plugin ID 267863

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-2025-423643 advisory.

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

 media: venus: fix use after free bug in venus_remove due to race condition

 in venus_probe, core->work is bound with venus_sys_error_handler, which is used to handle error. The code use core->sys_err_done to make sync work.
 The core->work is started in venus_event_notify.

 If we call venus_remove, there might be an unfished work. The possible sequence is as follows:

 CPU0 CPU1

 |venus_sys_error_handler venus_remove | hfi_destroy | venus_hfi_destroy | kfree(hdev); | |hfi_reinit |venus_hfi_queues_reinit |//use hdev

 Fix it by canceling the work in venus_remove.

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.
