CVE-2026-90023

CVE-2026-90023 is a null pointer dereference in the Linux kernel USB gadget f_mass_storage driver, specifically in fsg_common_set_num_buffers(). The root cause is that the earlier removal of fsg_num_buffers_validate() relied on Kconfig limits (2–256) for the buffer count n, but a user can write p...

CVE-2026-90019

CVE-2026-90019 affects the Linux kernel USB gadget subsystem. In the UVC function implementation, usb_put_function_instance() dereferences fi->fd to retrieve the module reference in the uvc_alloc_inst() error path. However, fd is not allocated until later in try_get_usb_function_instance(), so...

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-2026-89994

CVE-2026-89994 affects the Linux kernel 's fsl-edma DMA engine driver . The fsl-edma trace events store a pointer to struct fsl_edma_engine in the ringbuffer and dereference it during log output, at which point the pointer may already be invalid (use-after-free) . A local user with tracing access...

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...
