Descriptions

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

powerpc/powernv: Add a null pointer check to scom_debug_init_one()

kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure.
Add a null pointer check, and release 'ent' to avoid memory leaks.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: powerpc/powernv: agregue una verificación de puntero null a scom_debug_init_one() kasprintf() devuelve un puntero a la memoria asignada dinámicamente que puede ser NULL en caso de fallo. Agregue una verificación de puntero null y suelte 'ent' para evitar pérdidas de memoria.
