Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-003695)

medium Nessus Plugin ID 288451

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-2026-003695 advisory.

A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control this failure at probe time

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.
