CVE-2024-56604

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: avoid leaving dangling sk pointer in rfcomm_sock_alloc() bt_sock_alloc() attaches allocated sk object to the provided sock object. If rfcomm_dlc_alloc() fails, we release the sk object, but leave the dangling pointer in the sock object, which may cause use-after-free. Fix this by swapping calls to bt_sock_alloc() and rfcomm_dlc_alloc().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Bluetooth: RFCOMM: evitar dejar el puntero sk colgando en rfcomm_sock_alloc() bt_sock_alloc() adjunta el objeto sk asignado al objeto sock proporcionado. Si rfcomm_dlc_alloc() falla, liberamos el objeto sk, pero dejamos el puntero colgando en el objeto sock, lo que puede provocar un use-after-free. Solucione esto intercambiando las llamadas a bt_sock_alloc() y rfcomm_dlc_alloc().
