CVE-2026-98721 PUBLISHED

mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ

Assigner: Linux
Reserved: 25.09.2026 Published: 18.10.2026 Updated: 18.10.2026

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.
