Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002413)

high Nessus Plugin ID 287752

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-2026-002413 advisory.

The batadv_frag_merge_packets function in net/batman-adv/fragmentation.c in the B.A.T.M.A.N.
implementation in the Linux kernel through 3.18.1 uses an incorrect length field during a calculation of an amount of memory, which allows remote attackers to cause a denial of service (mesh-node system crash) via fragmented packets.

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.
