CVE-2022-48843 Open this link in a new tabHow to fix?
There is no fixed version for RHEL:9 kernel-core.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-core package and not the kernel-core 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:
drm/vrr: Set VRR capable prop only if it is attached to connector
VRR capable property is not attached by default to the connector It is attached only if VRR is supported. So if the driver tries to call drm core set prop function without it being attached that causes NULL dereference.
