CVE-2024-26964

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-26964
In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Add error handling in xhci_map_urb_for_dma Currently xhci_map_urb_for_dma() creates a temporary buffer and copies the SG list to the new linear buffer. But if the kzalloc_node() fails, then the following sg_pcopy_to_buffer() can lead to crash since it tries to memcpy to NULL pointer. So return -ENOMEM if kzalloc returns null pointer.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: xhci: agregar manejo de errores en xhci_map_urb_for_dma Actualmente, xhci_map_urb_for_dma() crea un búfer temporal y copia la lista SG en el nuevo búfer lineal. Pero si kzalloc_node() falla, entonces el siguiente sg_pcopy_to_buffer() puede provocar un fallo ya que intenta memcpy al puntero NULL. Entonces devuelve -ENOMEM si kzalloc devuelve un puntero nulo.
