CVE Details

Release Date:

2023-09-06

Description

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.\nWhen nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances.\nWe recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8.
