CVE-2026-64236

In CVE-2026-64236, the Linux kernel i2c/davinci driver was fixed to prevent a division-by-zero during probe when clock-frequency is missing from the device tree. The fallback DEFAULT_BUS_FREQ was defined in kHz as 100, but the device-tree property is in Hz. The probe divides the fallback value by...

EUVD-2026-48645

In the Linux kernel, the following vulnerability has been resolved: i2c: davinci: fix division by zero on missing clock-frequency When the 'clock-frequency' property is missing from the device tree, the driver falls back to DAVINCII2CDEFAULTBUSFREQ. However, this macro was defined in kHz 100,...

CVE-2026-7007

The Zephyr ext2 file system validates the on-disk superblock in ext2verifydisksuperblock subsys/fs/ext2/ext2impl.c before completing a mount. The validator checked the magic number, block size, revision and feature flags, but did not verify that the on-disk fields sblockspergroup and...

In the Linux kernel, the following vulnerability has been resolved: i2c: davinci: fix division by zero on missing clock-frequency When the 'clock-frequency' property is missing from the device tree, the driver falls back to DAVINCI I2C DEFAULT BUS FREQ. However, this macro was defined in kHz 100,...

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-2026-63931

A flaw was found in the Linux kernel's iio: chemical: scd30 driver. A local user can trigger a denial of service DoS by writing a zero fractional part to the samplingfrequency sysfs attribute. This action leads to a division-by-zero error within the kernel, causing the system to crash...

CVE-2026-10679

CVE-2026-10679 affects Zephyr’s DesignWare SPI driver (drivers/spi/spi_dw.c). The bug arises when the BAUDR divider is computed as info->clock_frequency / config->frequency without validating frequency, allowing a user-space configured frequency of 0. The spi_transceive syscall path copies ...

CVE-2026-63935

A flaw was found in the Linux kernel's NXP SAR Analog-to-Digital Converter ADC module. A local user can trigger a division-by-zero error by providing a zero or negative value to the samplingfrequency sysfs attribute. This vulnerability can lead to a denial of service DoS due to the kernel crashin...

CVE-2026-63933

A flaw was found in the Linux kernel's adis16260 gyroscope driver. A local user can trigger a division-by-zero error by writing a zero value to the samplingfrequency sysfs attribute. This can lead to a kernel panic, resulting in a system crash and a Denial of Service DoS...
