Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986815)

medium Nessus Plugin ID 267969

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-2025-986815 advisory.

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

crypto: qcom-rng - fix infinite loop on requests not multiple of WORD_SZ

The commit referenced in the Fixes tag removed the 'break' from the else branch in qcom_rng_read(), causing an infinite loop whenever 'max' is not a multiple of WORD_SZ. This can be reproduced e.g. by running:

kcapi-rng -b 67 >/dev/null

There are many ways to fix this without adding back the 'break', but they all seem more awkward than simply adding it back, so do just that.

Tested on a machine with Qualcomm Amberwing processor.

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.
