kernel: Linux kernel: Denial of Service in netfilter due to improper garbage collection

A flaw was found in the Linux kernel's netfilter component, specifically within the nftsetrbtree module. A local user with low privileges could exploit an issue where the garbage collection mechanism fails to properly release memory during interval expiration walks. This can lead to a memory leak...
