CVE-2026-10679

The DesignWare SPI driver drivers/spi/spidw.c computed the SPI BAUDR clock divider as info-clockfrequency / config-frequency without validating config-frequency. spitransceive is a Zephyr syscall and its verify handler drivers/spi/spihandlers.c copies the caller-supplied spiconfig from userspace...

CVE-2026-10679

The CVE-2026-10679 issue affects Zephyr’s DesignWare SPI driver (drivers/spi/spi_dw.c). The root cause is that the BAUDR clock divider was computed as info->clock_frequency / config->frequency without validating frequency, allowing a userspace thread with SPI access to pass frequency = 0, t...
