In the Linux kernel, the following vulnerability has been resolved:

iio: chemical: sps30i2c: fix buffer size in sps30i2creadmeas()

sizeof(num) evaluates to sizeof(sizet) (8 bytes on 64-bit) instead of the intended be32 element size (4 bytes). Use sizeof(meas) to correctly match the buffer element type.
