In the Linux kernel, the following vulnerability has been resolved: iio: adc: adi-axi-adc: Initialize state mutex The AXI ADC register access paths… (CVE-2026-98674)

The Linux kernel's Industrial I/O (iio) ADC driver for the ADI AXI ADC hardware had a synchronization vulnerability due to the state mutex (st->lock) not being initialized during the probe phase. Although the AXI ADC register access paths serialize transactions with this lock, the lack of initialization could cause race conditions or inconsistent state. The vulnerability was resolved by initializing the mutex before registering the backend driver.

The vulnerability could lead to improper serialization of register access transactions within the ADC driver, potentially causing race conditions or inconsistent hardware state. No specific exploitation details or impact scenarios are provided. There are no known exploits in the wild.

A fix has been applied to initialize the state mutex before registering the backend driver. Users should update to the Linux kernel version that includes this fix. Since no patch links or affected versions are provided, consult the official Linux kernel advisories or repositories for the fixed version.
