A flaw was found in the Linux kernel's netfilter subsystem. The global nature of the nft_object rhltable allows a local attacker to access objects that are being deallocated by other network namespaces. This can lead to a use-after-free vulnerability, potentially resulting in memory corruption or denial of service.
