In the Linux kernel, the following vulnerability has been resolved: net: inet6: do not leave a dangling sk pointer in inet6_create() sock_init_data() attaches the allocated sk pointer to the provided sock object. If inet6_create() fails later, the sk object is released, but the sock object retains the dangling sk pointer, which may cause use-after-free later. Clear the sock sk pointer on error.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: inet6: no deje un puntero sk colgando en inet6_create() sock_init_data() adjunta el puntero sk asignado al objeto sock proporcionado. Si inet6_create() falla más tarde, se libera el objeto sk, pero el objeto sock conserva el puntero sk colgando, lo que puede provocar un use-after-free más adelante. Borre el puntero sk sock en caso de error.
