There is no fixed version for RHEL:9 kernel-ipaclones-internal.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-ipaclones-internal package and not the kernel-ipaclones-internal 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:
idpf: return 0 size for RSS key if not supported
Returning -EOPNOTSUPP from function returning u32 is leading to cast and invalid size value as a result.
-EOPNOTSUPP as a size probably will lead to allocation fail.
Command: ethtool -x eth0 It is visible on all devices that don't have RSS caps set.
