Upgrade Oracle:9 rtla to version 0:5.14.0-284.11.1.el9_2 or higher.
This issue was patched in ELSA-2023-2458.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rtla package and not the rtla package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
