CVE-2024-50224
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
spi: spi-fsl-dspi: Fix crash when not using GPIO chip select
Add check for the return value of spi_get_csgpiod() to avoid passing a NULL pointer to gpiod_direction_output(), preventing a crash when GPIO chip select is not used.
