GHSA-WR98-XXCM-8GQW
Vulnerability from github – Published: 2026-10-18 18:32 – Updated: 2026-10-30 15:33In 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.
