CVE-2024-56567 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ad7780: fix division by zero in ad7780_write_raw()

In the ad7780_write_raw() val2 can be zero which might lead to a division by zero error in DIV_ROUND_CLOSEST(). The ad7780_write_raw() is based on iio_info’s write_raw. While val is explicitly declared that can be zero (in read mode) val2 is not specified to be non-zero.
