Описание
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ
The Cadence NAND interrupt handler uses both the IRQ lock and completion
object. Registering the IRQ before initializing them leaves a window in
which a pending interrupt can access uninitialized synchronization state.
Initialize them before registering the handler.
A flaw was found in the Linux kernel's Cadence NAND controller driver. The driver registers its interrupt handler before initializing the internal synchronization lock and completion objects. A pending interrupt during initialization can trigger the handler to access this uninitialized state, potentially resulting in a system crash and Denial of Service (DoS).
