Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: hwmon: mlxreg-fan Returns a non-zero value when the fan’s current state is enforced from sysfs. The minimum fan speed can be enforced from sysfs. For example, setting the current fan speed to 20 is used to force the fan speed ...

The vulnerability of the mlxreg_fan_set_cur_state() function in the drivers/hwmon/mlxreg-fan.c module of the Linux operating system’s hardware monitoring driver allows a hacker to cause a service failure.

The vulnerability of the mlxregfansetcurstate function in the drivers/hwmon/mlxreg-fan.c module of the Linux device monitoring driver is related to the execution of operations outside of the buffer boundaries. Exploiting this vulnerability could allow an attacker to cause a system failure...
