Unity Linux 20.1050e Security Update: kernel (UTSA-2026-007521)

medium Nessus Plugin ID 307149

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-2026-007521 advisory.

In the Linux kernel, the following vulnerability has been resolved:

be2net: pass wrb_params in case of OS2BMC

be_insert_vlan_in_pkt() is called with the wrb_params argument being NULL at be_send_pkt_to_bmc() call site. This may lead to dereferencing a NULL pointer when processing a workaround for specific packet, as commit bc0c3405abbb (be2net: fix a Tx stall bug caused by a specific ipv6 packet) states.

The correct way would be to pass the wrb_params from be_xmit().

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.
