Unity Linux 20.1070a Security Update: kernel (UTSA-2025-990043)

medium Nessus Plugin ID 272570

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-2025-990043 advisory.

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

 gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully

 When running gpio test on nxp-ls1028 platform with below command gpiomon --num-events=3 --rising-edge gpiochip1 25 There will be a warning trace as below:
 Call trace:
 free_irq+0x204/0x360 lineevent_free+0x64/0x70 gpio_ioctl+0x598/0x6a0
 __arm64_sys_ioctl+0xb4/0x100 invoke_syscall+0x5c/0x130 ......
 el0t_64_sync+0x1a0/0x1a4 The reason of this issue is that calling request_threaded_irq() function failed, and then lineevent_free() is invoked to release the resource. Since the lineevent_state::irq was already set, so the subsequent invocation of free_irq() would trigger the above warning call trace. To fix this issue, set the lineevent_state::irq after the IRQ register successfully.

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.
