Unity Linux 20.1070a Security Update: kernel (UTSA-2025-990389)

medium Nessus Plugin ID 274323

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-2025-990389 advisory.

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

 HID: core: remove unnecessary WARN_ON() in implement()

 Syzkaller hit a warning [1] in a call to implement() when trying to write a value into a field of smaller size in an output report.

 Since implement() already has a warn message printed out with the help of hid_warn() and value in question gets trimmed with:
 ...
 value &= m;
 ...
 WARN_ON may be considered superfluous. Remove it to suppress future syzkaller triggers.

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.
