  3. CVE-2024-26653
In the Linux kernel, the following vulnerability has been resolved: usb: misc: ljca: Fix double free in error handling path When auxiliary_device_add() returns error and then calls auxiliary_device_uninit(), callback function ljca_auxdev_release calls kfree(auxdev->dev.platform_data) to free the parameter data of the function ljca_new_client_device. The callers of ljca_new_client_device shouldn't call kfree() again in the error handling path to free the platform data. Fix this by cleaning up the redundant kfree() in all callers and adding kfree() the passed in platform_data on errors which happen before auxiliary_device_init() succeeds .

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: misc: ljca: corrige el doble libre en la ruta de manejo de errores Cuando auxiliar_device_add() devuelve un error y luego llama a auxiliar_device_uninit(), la función de devolución de llamada ljca_auxdev_release llama a kfree(auxdev->dev.platform_data ) para liberar los datos de los parámetros de la función ljca_new_client_device. Las personas que llaman a ljca_new_client_device no deberían volver a llamar a kfree() en la ruta de manejo de errores para liberar los datos de la plataforma. Solucione este problema limpiando el kfree() redundante en todas las personas que llaman y agregando kfree() los datos de plataforma pasados en los errores que ocurren antes de queauxiliar_device_init() tenga éxito.
