In the Linux kernel, the following vulnerability has been resolved: af_packet: avoid erroring out after sock_init_data() in packet_create() After sock_init_data() the allocated sk object is attached to the provided sock object. On error, packet_create() frees the sk object leaving the dangling pointer in the sock object on return. Some other code may try to use this pointer and cause use-after-free.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: af_packet: evitar errores después de sock_init_data() en packet_create() Después de sock_init_data(), el objeto sk asignado se adjunta al objeto sock proporcionado. En caso de error, packet_create() libera el objeto sk dejando el puntero colgando en el objeto sock al regresar. Es posible que algún otro código intente usar este puntero y provoque un error de use-after-free.
