CVE-2026-43380

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the pmbus/q54sj108a2 driver. This vulnerability, a stack buffer overflow, occurs in the q54sj108a2debugfsread function due to incorrect arguments passed to the bin2hex function. This flaw allows data to be written past th...

CVE-2026-43165

A flaw was found in the Linux kernel's hwmon subsystem, specifically in the nct7363 driver. This resource leak occurs in the nct7363presentpwmfanin function because a device node reference is not properly released after being acquired. An attacker with local access could potentially exploit this ...

CVE-2026-31770

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the occ driver. During early boot or when no sensor samples have been collected, the occshowpower1 function can attempt to divide by zero. A local attacker could exploit this condition, leading to a kernel crash and a...

CVE-2026-31582

A flaw was found in the Linux kernel's hwmon subsystem. A local attacker, by disconnecting a USB device, could trigger a use-after-free vulnerability in the powerz driver. This occurs when the driver attempts to access a Universal Serial Bus Request Block URB after it has been freed during the...

CVE-2026-31486

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the pmbus/core module. The regulator operations, which manage power management bus PMBus registers and shared data, were not adequately protected by a mutex a mechanism to prevent simultaneous access to shared resources...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A potential invalid memory access issue has been identified in the Linux kernel, specifically in the asus-ec-sensors component of the hwmon subsystem. The find ec sensor index function...

kernel: hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs

A vulnerability was found in the Linux kernel's hwmon subsystem, specifically in the mlxreg-fan driver. The issue arises when the driver’s sysfs interface for controlling fan speed does not properly handle cases where the requested minimum fan speed exceeds the maximum allowable value. When the...
