CVE-2026-80679

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

Description A NULL pointer dereference can occur in the dasd release space() function. The issue arises because the function uses a logical AND operator when checking the implementation of the is ese() discipline function to determine if a device is an ESE DASD, causing the function to be called even if the function pointer is NULL.

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