Linux Kernel Netfilter nf_tables Use-After-Free Vulnerability via SET_ID Reference

A use-after-free vulnerability has been identified in the Linux kernel's netfilter component, specifically within nf_tables. The issue arises when SET_ID references another table during lookups for sets. If the referenced table is removed, the lookup may retain a reference to a freed set, leading to potential exploitation. This vulnerability affects several versions of the Linux kernel.

Impact

Exploitation of this vulnerability can lead to a use-after-free condition, potentially allowing for memory corruption or arbitrary code execution.
