Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-001983)
medium Nessus Plugin ID 286496
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-2026-001983 advisory.The ieee80211_radiotap_iterator_init function in net/wireless/radiotap.c in the Linux kernel before 3.11.7 does not check whether a frame contains any data outside of the header, which might allow attackers to cause a denial of service (buffer over-read) via a crafted header.
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.See Also
