  3. CVE-2024-40903
In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpm: fix use-after-free case in tcpm_register_source_caps There could be a potential use-after-free case in tcpm_register_source_caps(). This could happen when: * new (say invalid) source caps are advertised * the existing source caps are unregistered * tcpm_register_source_caps() returns with an error as usb_power_delivery_register_capabilities() fails This causes port->partner_source_caps to hold on to the now freed source caps. Reset port->partner_source_caps value to NULL after unregistering existing source caps.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: typec: tcpm: arreglar el caso de use-after-free en tcpm_register_source_caps Podría haber un posible caso de use-after-free en tcpm_register_source_caps(). Esto podría suceder cuando: * se anuncian límites de fuente nuevos (por ejemplo, no válidos) * los límites de fuente existentes no están registrados * tcpm_register_source_caps() devuelve un error ya que usb_power_delivery_register_capabilities() falla Esto hace que port->partner_source_caps conserve los límites de fuente ahora liberados. Restablezca el valor de puerto->partner_source_caps a NULL después de cancelar el registro de los límites de origen existentes.
