CVE-2024-35790

  2. Vulnerabilities (CVE)
  3. CVE-2024-35790
In the Linux kernel, the following vulnerability has been resolved: usb: typec: altmodes/displayport: create sysfs nodes as driver's default device attribute group The DisplayPort driver's sysfs nodes may be present to the userspace before typec_altmode_set_drvdata() completes in dp_altmode_probe. This means that a sysfs read can trigger a NULL pointer error by deferencing dp->hpd in hpd_show or dp->lock in pin_assignment_show, as dev_get_drvdata() returns NULL in those cases. Remove manual sysfs node creation in favor of adding attribute group as default for devices bound to the driver. The ATTRIBUTE_GROUPS() macro is not used here otherwise the path to the sysfs nodes is no longer compliant with the ABI.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: usb: typec: altmodes/displayport: cree nodos sysfs como grupo de atributos de dispositivo predeterminado del controlador Los nodos sysfs del controlador DisplayPort pueden estar presentes en el espacio de usuario antes de que typec_altmode_set_drvdata() se complete en dp_altmode_probe. Esto significa que una lectura de sysfs puede desencadenar un error de puntero NULL al hacer una diferencia entre dp->hpd en hpd_show o dp->lock en pin_assignment_show, ya que dev_get_drvdata() devuelve NULL en esos casos. Elimine la creación manual de nodos sysfs en favor de agregar un grupo de atributos como predeterminado para los dispositivos vinculados al controlador. La macro ATTRIBUTE_GROUPS() no se utiliza aquí; de lo contrario, la ruta a los nodos sysfs ya no cumple con la ABI.
