Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989160)

medium Nessus Plugin ID 273603

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-2025-989160 advisory.

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

 scsi: libfc: Fix potential NULL pointer dereference in fc_lport_ptp_setup()

 fc_lport_ptp_setup() did not check the return value of fc_rport_create() which can return NULL and would cause a NULL pointer dereference. Address this issue by checking return value of fc_rport_create() and log error message on fc_rport_create() failed.

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.
