Descriptions

A use-after-free flaw was found in the Linux kernel’s pipes functionality in how a user performs manipulations with the pipe post_one_notification() after free_pipe_info() that is already called. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Se ha encontrado un fallo de uso después de libre en la funcionalidad de tuberías del kernel de Linux en la forma en que un usuario realiza manipulaciones con la tubería post_one_notification() después de free_pipe_info() que ya ha sido llamada. Este defecto permite a un usuario local bloquear o potencialmente escalar sus privilegios en el sistema
