CVE-2026-90020

CVE-2026-90020 affects the Linux kernel USB gadget subsystem. The vulnerability is a race condition in gadget_dev_ioctl(): the function reads dev->gadget before acquiring dev->lock, but checks dev->state only after acquiring the lock. A concurrent bind can change the device state between...

CVE-2026-89993

CVE-2026-89993 affects the Linux kernel in the dmaengine dw-edma driver. The root cause is an initialization-order bug: dw_edma_irq_request() passes struct dw_edma_irq to request_irq() before dw_edma_channel_setup() fills the back pointer. As a result, a shared interrupt can enter the handler wit...
