Descriptions
kernel/ucount.c in the Linux kernel 5.14 through 5.16.4, when unprivileged user namespaces are enabled, allows a use-after-free and privilege escalation because a ucounts object can outlive its namespace.
El archivo kernel/ucount.c en el kernel de Linux versiones 5.14 hasta 5.16.4, cuando los espacios de nombres de los usuarios no privilegiados están habilitados, permite un uso de memoria previamente liberada y una escalada de privilegios porque un objeto ucounts puede sobrevivir a su espacio de nombres
