mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ
Type: advisorySources: OSV
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.
