CVE-2026-43340

Summary (CVE-2026-43340): The Linux kernel COMEDI subsystem contains a spinlock (dev->spinlock) in struct comedi_device that can be reinitialized when a COMEDI device is reattached to different low-level drivers via COMEDI_DEVCONFIG. This race can occur if multiple drivers with different lockd...

CVE-2026-43307

The CVE concerns the Linux kernel iio: accel: adxl380 driver. The interrupt handler can miscalculate FIFO entries because the sensor fills FIFO one sample at a time while batches are read, causing the FIFO status to report a non-multiple of N. This can cause the driver to read more entries than p...
