CVE-2018-10938

A flaw was found in the Linux kernel present since v4.0-rc1 and through v4.13-rc4. A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw.

Se ha detectado un error en el kernel de Linux presente desde v4.0-rc1 y hasta v4.13-rc4. Un paquete de red manipulado enviado de forma remota por un atacante podría forzar al kernel a entrar en un bucle infinito en la función cipso_v4_optptr() en net/ipv4/cipso_ipv4.c, lo que conduce a una denegación de servicio (DoS). Cierta configuración que no es por defecto en LSM (Linux Security Module) y NetLabel debería configurarse en un sistema antes de que un atacante pueda aprovechar este error.
