NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-modules-core package and not the kernel-64k-debug-modules-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:

netfilter: nft_limit: reject configurations that cause integer overflow

Reject bogus configs where internal token counter wraps around. This only occurs with very very large requests, such as 17gbyte/s.

Its better to reject this rather than having incorrect ratelimit.
