Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-151299)

high Nessus Plugin ID 378379

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-2026-151299 advisory.

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

HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature

sensor_hub_get_feature() clamps its return value to the caller's buffer size, but the copy loop still copies field->report_size / 8 bytes for each report value. A malicious HID descriptor can advertise a large feature field size while an IIO caller supplies a small stack buffer, such as a single s32, causing an out-of-bounds write.

HID core stores parsed report values in __s32 slots and clamps extracted values to 32 bits. Reject feature fields that require more than one slot per value, guard the total byte count calculation, and clamp each per-value copy to the remaining caller buffer.

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.
