CVE-2025-68224

UFS startup fault via uninitialized SCSI tag set

Published Dec 16, 2025 · Updated Dec 16, 2025

The Linux Kernel SCSI core received this identifier for a scsi_host_busy() initialization regression during UFS driver probing. The function called blk_mq_tagset_busy_iter() before the host tag set ops field had been initialized, producing an SRCU lock trace during startup. Kernel.org later rejected the CVE and removed every affected-version reference, so the identifier no longer represents a confirmed vulnerability.
