Description OSIDB Bzimport 2026-10-18 15:51:31 UTC
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.
