Unity Linux 20.1070e Security Update: kernel (UTSA-2026-013341)

low Nessus Plugin ID 307961

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-2026-013341 advisory.

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

 mfd: pcf50633-adc: Fix potential memleak in pcf50633_adc_async_read()

 `req` is allocated in pcf50633_adc_async_read(), but adc_enqueue_request() could fail to insert the `req` into queue.
 We need to check the return value and free it in the case of failure.

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.
