Description

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795. A use-after-free vulnerability was found in the netfilter: nf_tables component in the Linux kernel due to a missing error handling in the abort path of NFT_MSG_NEWRULE. This flaw allows a local attacker with CAP_NET_ADMIN access capability to cause a local privilege escalation problem.
