CVE-2024-56601

In the Linux kernel, the following vulnerability has been resolved: net: inet: do not leave a dangling sk pointer in inet_create() sock_init_data() attaches the allocated sk object to the provided sock object. If inet_create() fails later, the sk object is freed, but the sock object retains the dangling pointer, which may create use-after-free later. Clear the sk pointer in the sock object on error.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: inet: no deje un puntero sk colgando en inet_create() sock_init_data() adjunta el objeto sk asignado al objeto sock proporcionado. Si inet_create() falla más tarde, el objeto sk se libera, pero el objeto sock conserva el puntero colgando, lo que puede crear un use-after-free más tarde. Borre el puntero sk en el objeto sock en caso de error.
