CVE-2026-31749

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the comedi ni atmio16d driver where the atmio16d detach() handler function calls reset atmio16d() unconditionally during a failed attach process. If the atmio16d attach() function returns an error before the device is fully initialized, dev->iobase may remain 0, leading to undesired writes to low I/O port addresses. Additionally, dev->private may be NULL, resulting in null pointer dereferences (an attempt to access a memory location that does not exist).

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
