CVE-2022-2586: Linux Kernel Use-After-Free Vulnerability

Published Aug 3, 2022
·
Updated

A use-after-free flaw was found in nftables cross-table in the net/netfilter/nftablesapi.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation.

Other sources

It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted.

— Microsoft

Linux Kernel contains a use-after-free vulnerability in the nftobject, allowing local attackers to escalate privileges.

— CISA

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of nftobjects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.

— ZDI
