medium Nessus Plugin ID 305460

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-2026-006769 advisory.

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

 pcmcia: Fix a NULL pointer dereference in __iodyn_find_io_region()

 In __iodyn_find_io_region(), pcmcia_make_resource() is assigned to res and used in pci_bus_alloc_resource(). There is a dereference of res in pci_bus_alloc_resource(), which could lead to a NULL pointer dereference on failure of pcmcia_make_resource().

 Fix this bug by adding a check of res.
