medium Nessus Plugin ID 288015

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-2026-004419 advisory.

A missing CAP_NET_RAW check in NFC socket creation in net/nfc/rawsock.c in the Linux kernel before 5.8.2 could be used by local attackers to create raw sockets, bypassing security mechanisms, aka CID-26896f01467a.

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.
