Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-003547)

medium Nessus Plugin ID 286301

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-2026-003547 advisory.

Memory leak in the hwsim_new_radio_nl function in drivers/net/wireless/mac80211_hwsim.c in the Linux kernel through 4.15.9 allows local users to cause a denial of service (memory consumption) by triggering an out-of-array error case.

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.
