[REJECTED CVE] A vulnerability in the Linux kernel's hwmon subsystem (w83627ehf driver) has been identified, where writing large negative values (e.g., -9223372036854775808) to limit attributes caused an underflow due to improper ordering of operations in DIV_ROUND_CLOSEST(). An attacker with write access to these attributes could potentially trigger unexpected behavior or system instability.
