Doc Text:	A flaw was found in the Linux kernel's Analog Devices AXI ADC driver. This vulnerability can lead to a denial of service (DoS) due to an uninitialized synchronization lock (mutex) used during register access operations. A local user could trigger this issue during device interactions, causing improper locking behavior and resulting in a kernel crash.	Story Points:	---

Description OSIDB Bzimport 2026-10-18 15:57:15 UTC

In the Linux kernel, the following vulnerability has been resolved:

iio: adc: adi-axi-adc: Initialize state mutex

The AXI ADC register access paths serialize transactions with st->lock,
but probe does not initialize it. Initialize the mutex before registering
the backend.
