CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2023-3777 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-3777
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When 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. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. Una vulnerabilidad de Use-After-Free en el componente netfilter: nf_tables del kernel de Linux puede explotarse para lograr una escalada de privilegios local. Cuando nf_tables_delrule() vacía las reglas de la tabla, no se verifica si la cadena está vinculada y la regla del propietario de la cadena también puede liberar los objetos en determinadas circunstancias. Recomendamos actualizar al pasado commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. A use-after-free flaw was found in the Linux kernel's netfilter: nf_tables component, which can be exploited to achieve local privilege escalation. • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8 https://kernel.dance/6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-3777 https://bugzilla.redhat.com/show_bug.cgi?id=223 • CWE-416: Use After Free •

CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-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 •
