CVE-2024-50224

Local system crash via unchecked GPIO descriptor

Published Nov 9, 2024 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel's spi-fsl-dspi driver allows local users to crash affected systems during device setup. In dspi_setup, spi_get_csgpiod() returns NULL when GPIO chip select is unused, but the driver passes that value to gpiod_direction_output() without checking it. Reachability requires a system using the affected DSPI driver and a non-GPIO chip-select configuration; the resulting kernel oops interrupts service.
