In the Linux kernel, the following vulnerability has been resolved: s390/dasd: add missing discipline function Fix crash with illegal operation exception in dasd_device_tasklet. Commit b72949328869 ("s390/dasd: Prepare for additional path event handling") renamed the verify_path function for ECKD but not for FBA and DIAG. This leads to a panic when the path verification function is called for a FBA or DIAG device. Fix by defining a wrapper function for dasd_generic_verify_path().

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-988756 advisory.
