# A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve…

The Linux kernel's netfilter nf_tables component has a use-after-free bug. A local user can use it to gain root privileges on the machine.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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



The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT.



We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.
