CVE-2026-80552

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

Description An issue exists in the s390/vfio ccw component where the system failed to properly clamp the index for read/write regions to the range of the capabilities. While the capability chain implementation included this restriction, it was neglected for existing read/write regions, potentially allowing out-of-range index access.

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