Linux Kernel Netfilter nf_tables Stack Leak Vulnerability

A vulnerability in the Linux kernel's netfilter component, specifically in nf_tables, has been addressed. The issue involved a stack leak into userspace, which could occur because registers were not properly initialized in the nft_do_chain() function. This vulnerability could potentially be exploited to leak sensitive information from the kernel stack to userspace.

Impact

The vulnerability could lead to unintentional information disclosure by leaking data from the kernel stack into userspace.
