Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A sign-extension bug exists in the
scd30 chemical IIO driver. The issue occurs when a float32 value is bitwise ANDed with ~BIT(31), resulting in a value of 0xFFFFFFFF7FFFFFFF that corrupts the exponent. The fix involves refactoring variable declarations for mantissa and exp, initializing sign separately, and replacing manual bit manipulation with the FIELD GET() function from linux/bitfield.h.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
