  "cwe" : "CWE-824",
  "details" : [ "A flaw was found in the `ni_atmio16d` driver within the Comedi (Comedi is a collection of drivers for data acquisition equipment) subsystem of the Linux kernel. This vulnerability occurs when an error during the driver's attach process causes the cleanup function (`atmio16d_detach()`) to be called with uninitialized device data. This can lead to undesired writes to low I/O port addresses or null pointer dereferences, potentially resulting in system instability or a denial of service (DoS) for a local user." ],
