"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-003757 advisory.

    A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before
    4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware
    could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.

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.");
