CVE-2024-45828

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-45828
In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request Bus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when the ring is being stopped. Depending on timing between ring stop request completion, interrupt handler removal and code execution this may lead to a NULL pointer dereference in hci_dma_irq_handler() if it gets to run after the io_data pointer is set to NULL in hci_dma_cleanup(). Prevent this my masking the ring interrupts before ring stop request.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: i3c: mipi-i3c-hci: Enmascarar interrupciones del anillo antes de la solicitud de detención del anillo La ruta de desinfección del bus en modo DMA puede activar una interrupción RING_OP_STAT cuando se detiene el anillo. Dependiendo del tiempo entre la finalización de la solicitud de detención del anillo, la eliminación del controlador de interrupciones y la ejecución del código, esto puede provocar una desreferencia de puntero NULL en hci_dma_irq_handler() si se ejecuta después de que el puntero io_data se establezca en NULL en hci_dma_cleanup(). Evite esto enmascarando las interrupciones del anillo antes de la solicitud de detención del anillo.
