A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free. We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.
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. La adición y eliminación de reglas de enlaces de cadena dentro de la misma transacción provoca que se produzca un use-after-free. Recomendamos actualizar después del compromiso f15f29fd4779be8a418b66e9d52979bb6d6c2325.
