CVE-2023-31248 – Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-31248
Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()` failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace Vulnerabilidad de Escalada de Privilegios Locales de Use-After-Free de Linux nftables; 'nft_chain_lookup_byid()' no pudo comprobar si una cadena estaba activa y CAP_NET_ADMIN está en cualquier espacio de nombres de usuario o red A use-after-free flaw was found in the Linux kernel's Netfilter module in net/netfilter/nf_tables_api.c in nft_chain_lookup_byid. This flaw allows a local attacker to cause a local privilege escalation issue due to a missing cleanup. 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 nft_chains. The issue results from the lack of validating the status of a chain while processing lookup on the chain. • http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html http://www.openwall.com/lists/oss-security/2023/07/05/2 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/RGZC5XOANA75OJ4XARBBXYSLDKUIJI5E https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.or • CWE-416: Use After Free •
