Descriptions

In the Linux kernel, the following vulnerability has been resolved: smb3: fix temporary data corruption in insert range insert range doesn't discard the affected cached region
so can risk temporarily corrupting file data. Also includes some minor cleanup (avoiding rereading
inode size repeatedly unnecessarily) to make it clearer.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: smb3: corrige la corrupción de datos temporales en el rango de inserción. El rango de inserción no descarta la región en caché afectada, por lo que puede correr el riesgo de dañar temporalmente los datos del archivo. También incluye una limpieza menor (evitando volver a leer el tamaño del inodo repetidamente innecesariamente) para hacerlo más claro.
