CVE-2026-64236 i2c: davinci: fix division by zero on missing clock-frequency

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-2026-64236

The CVE-2026-64236 issue affects the Linux kernel i2c/davinci driver: if the device-tree clock-frequency is missing, the driver falls back to DAVINCI_I2C_DEFAULT_BUS_FREQ. The macro was defined in kHz (100), but the property is in Hz, causing the probe to divide by 1000 and produce dev->bus_fr...

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,...

Linux kernel block-level support Heap Buffer Overflow DoS

The vulnerability of the calclcoefs function in the block/blk-iocost.c module of the Linux kernel’s block-level support mechanism is related to insufficient checking of input data when dividing by zero. Exploiting this vulnerability could allow an attacker to cause a service failure...

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...
