https://notcve.org/view.php?id=CVE-2021-20177
A flaw was found in the Linux kernel's implementation of string matching within a packet. A privileged user (with root or CAP_NET_ADMIN) when inserting iptables rules could insert a rule which can panic the system. Kernel before kernel 5.5-rc1 is affected. Se encontró un fallo en la implementación del kernel de Linux de la coincidencia de cadenas dentro de un paquete. Un usuario privilegiado (con root o función CAP_NET_ADMIN) cuando se insertan las reglas de iptables podría insertar una regla que puede causar pánico en el sistema. • https://bugzilla.redhat.com/show_bug.cgi?id=1914719 • CWE-125: Out-of-bounds Read •
