Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: hwmon: adt7470 Fixed a divide-by-zero crash in the fan speed reading using TOCTOU. If the fan data becomes 0 between the FANDATAVALID check and the FANPERIODTORPM conversion, it will cause a divide-by-zero crash due to a race...

CVE-2026-74546

A flaw was found in the Linux kernel's hwmon hardware monitoring subsystem, specifically within the adt7470 driver. A local attacker could exploit a time-of-check to time-of-use TOCTOU race condition. If fan data becomes zero between a validation check and a conversion operation, it can lead to a...

CVE-2026-74547

A flaw was found in the Linux kernel's hwmon adt7470 component. A local user can exploit this by configuring the 'autoupdateinterval' to zero via sysfs while 'numtempsensors' is also set to zero. This combination forces the background thread into an unbounded busy-loop, consuming CPU resources an...

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...
