CVE-2026-74546

CVE-2026-74546 affects the Linux kernel hwmon adt7470 driver. A TOCTOU race can occur if fan data becomes 0 between the FAN_DATA_VALID() check and the FAN_PERIOD_TO_RPM() conversion, causing a divide-by-zero crash. The issue is mitigated by reading fan data once to prevent a concurrent update fro...
