CVE-2023-39189: Kernel: netfilter: nftables out-of-bounds read in nf_osf_match_one()

Published Jul 26, 2023
·
Updated

A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnlosfaddcallback function did not validate the user mode controlled optnum field. This flaw allows a local privileged (CAPNETADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.

Other sources

An out-of-bounds read issue was found in the Linux kernel in the nfosfmatchone() function, which is used for nftables OS fingerprinting. This flaw requires CAPNETADMIN to be exploited and could lead to information disclosure.

— Red Hat

Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by an out-of-bounds read flaw in the nfnlosfaddcallback function in the Netfilter subsystem. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service condition.
