CVE-2024-58009

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc A NULL sock pointer is passed into l2cap_sock_alloc() when it is called from l2cap_sock_new_connection_cb() and the error handling paths should also be aware of it. Seemingly a more elegant solution would be to swap bt_sock_alloc() and l2cap_chan_create() calls since they are not interdependent to that moment but then l2cap_chan_create() adds the soon to be deallocated and still dummy-initialized channel to the global list accessible by many L2CAP paths. The channel would be removed from the list in short period of time but be a bit more straight-forward here and just check for NULL instead of changing the order of function calls. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Bluetooth: L2CAP: gestionar puntero sock NULL en l2cap_sock_alloc Se pasa un puntero sock NULL a l2cap_sock_alloc() cuando se llama desde l2cap_sock_new_connection_cb() y las rutas de gestión de errores también deberían tenerlo en cuenta. Aparentemente, una solución más elegante sería intercambiar las llamadas bt_sock_alloc() y l2cap_chan_create() ya que no son interdependientes en ese momento, pero luego l2cap_chan_create() agrega el canal que pronto se desasignará y aún tiene inicialización ficticia a la lista global accesible por muchas rutas L2CAP. El canal se eliminaría de la lista en un corto período de tiempo, pero aquí sería un poco más directo y solo verificaría si es NULL en lugar de cambiar el orden de las llamadas de función. Encontrado por Linux Verification Center (linuxtesting.org) con la herramienta de análisis estático SVACE.
