Descriptions

In the Linux kernel, the following vulnerability has been resolved:

tracing: Consider the NULL character when validating the event length

strlen() returns a string length excluding the null byte. If the string
length equals to the maximum buffer length, the buffer will have no
space for the NULL terminating character.

This commit checks this condition and returns failure for it.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rastreo: considerar el carácter NULL al validar la longitud del evento strlen() devuelve una longitud de cadena que excluye el byte nulo. Si la longitud de la cadena es igual a la longitud máxima del búfer, el búfer no tendrá espacio para el carácter de terminación NULL. Esta confirmación verifica esta condición y devuelve un error.
