How to fix?

There is no fixed version for RHEL:9 kernel-rt-devel-matched.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-devel-matched package and not the kernel-rt-devel-matched package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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

PCI: keystone: Fix NULL pointer dereference in case of DT error in ks_pcie_setup_rc_app_regs()

If IORESOURCE_MEM is not provided in Device Tree due to any error, resource_list_first_type() will return NULL and pci_parse_request_of_pci_ranges() will just emit a warning.

This will cause a NULL pointer dereference. Fix this bug by adding NULL return check.
