A flaw was found in the Linux kernel's Chips&Media Wave5 video driver. A local user could trigger a Denial of Service (DoS) by causing a race condition during device release. When closing a video stream, the driver releases internal memory structures before removing the instance from the active list, allowing an interrupt handler to access freed memory and crash the system.
