Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002520)

critical Nessus Plugin ID 287133

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-2026-002520 advisory.

Stack-based buffer overflow in the ttusbdecfe_dvbs_diseqc_send_master_cmd function in drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel before 3.17.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via a large message length in an ioctl call.

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.
