  3. CVE-2024-56603
In the Linux kernel, the following vulnerability has been resolved: net: af_can: do not leave a dangling sk pointer in can_create() On error can_create() frees the allocated sk object, but sock_init_data() has already attached it to the provided sock object. This will leave a dangling sk pointer in the sock object and may cause use-after-free later.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: af_can: no deje un puntero sk colgando en can_create() En caso de error, can_create() libera el objeto sk asignado, pero sock_init_data() ya lo ha adjuntado al objeto sock proporcionado. Esto dejará un puntero sk colgando en el objeto sock y puede provocar un uso posterior a la liberación más adelante.
