CVE-2026-68182

A flaw was found in the Linux kernel's comedi_parport driver. A local user could trigger a premature interrupt, potentially due to incorrect initialization order of hardware registers or an invalid user-supplied I/O port address. This could lead to a general protection fault, resulting in a system crash and a denial of service.

This issue affects comedi parallel port devices. Premature interrupt can call comedi helpers before subdevice is fully initialized. Systems without comedi_parport are not affected.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the comedi_parport module from loading. See https://access.redhat.com/solutions/41278 for instructions.
