Description
A flaw was found in the i2c davinci driver of the Linux kernel. When the 'clock-frequency' property is missing from the device tree, the driver's fallback mechanism can lead to a division-by-zero error. This vulnerability can be triggered by a local attacker providing a malformed device tree, resulting in a kernel panic and a denial of service.
