CVSS: 7.8EPSS: 0%CPEs: 15EXPL: 2CVE-2023-35001 – Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability
https://notcve.org/view.php?id=CVE-2023-35001
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace Vulnerabilidad de Lectura/Escritura en nftables Fuera de los Límites del kernel de Linux; nft_byteorder administra incorrectamente los contenidos de registro de VM cuando CAP_NET_ADMIN está en cualquier espacio de nombres de usuario o red An out-of-bounds (OOB) memory access flaw was found in the Netfilter module in the Linux kernel's nft_byteorder_eval in net/netfilter/nft_byteorder.c. A bound check failure allows a local attacker with CAP_NET_ADMIN access to cause a local privilege escalation issue due to incorrect data alignment. 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 processing of nft chains. The issue results from incorrect pointer scaling, which can result in a memory access past the end of an array. • https://github.com/synacktiv/CVE-2023-35001 https://github.com/syedhafiz1234/nftables-oob-read-write-exploit-CVE-2023-35001- 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/2023/07/05/3 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.debian.org/debian-lts-announce/2024/01/m • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

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 •

A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.netapp.com/advisory/ntap-20230929-0006 https://www.debian.org/security/2023/dsa-5480 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-1206 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2023-3390 – Use-after-free in Linux kernel's netfilter subsystem
https://notcve.org/view.php?id=CVE-2023-3390
A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97. Se encontró una vulnerabilidad de use-after-free en el subsistema netfilter del kernel de Linux en net/netfilter/nf_tables_api.c. El manejo de errores mal manejado con NFT_MSG_NEWRULE permite usar un puntero colgante en la misma transacción que causa una vulnerabilidad de use-after-free. Esta falla permite que un atacante local con acceso de usuario cause un problema de escalada de privilegios. • http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=1240eb93f0616b21c675416516ff3d74798fdc97 https://kernel.dance/1240eb93f0616b21c675416516ff3d74798fdc97 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.netapp.com/advisory/ntap-20230818-0004 https://www.debian.org/security/2023/dsa-5448 https&# • CWE-416: Use After Free •
