CVE-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 •
