Summary
Use-after-free in Linux kernel's netfilter: nf_tables component
Details

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

The function nftpipapowalk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.

We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.
