Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002352)

medium Nessus Plugin ID 287629

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-2026-002352 advisory.

The udp_v6_push_pending_frames function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system 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.
