  "details": "In the Linux kernel, the following vulnerability has been resolved:  spi: spi-fsl-lpspi: fix teardown order issue (UAF)  There is a teardown order issue in the driver. The SPI controller is registered using devm_spi_register_controller(), which delays unregistration of the SPI controller until after the fsl_lpspi_remove() function returns.  As the fsl_lpspi_remove() function synchronously tears down the DMA channels, a running SPI transfer triggers the following NULL pointer dereference due to use after free:  | fsl_lpspi 42550000.spi: I/O Error in DMA RX | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 [...] | Call trace: |  fsl_lpspi_dma_transfer+0x260/0x340 [spi_fsl_lpspi] |  fsl_lpspi_transfer_one+0x198/0x448 [spi_fsl_lpspi] |  spi_transfer_one_message+0x49c/0x7c8 |  __spi_pump_transfer_message+0x120/0x420 |  __spi_sync+0x2c4/0x520 |  spi_sync+0x34/0x60 |  spidev_message+0x20c/0x378 [spidev] |  spidev_ioctl+0x398/0x750 [spidev] [...]  Switch from devm_spi_register_controller() to spi_register_controller() in fsl_lpspi_probe() and add the corresponding spi_unregister_controller() in fsl_lpspi_remove().",
