scsi target dbroot

About this tag
The scsi target dbroot tag covers a Linux kernel vulnerability (CVE-2026-23292) involving recursive locking in the configfs SCSI target subsystem. The bug occurs in target_core_item_dbroot_store(), where a configfs path can be reopened while holding a semaphore, leading to a deadlock risk. The fix replaces filp_open() with kern_path() to avoid this issue. Discussions focus on kernel synchronization, path validation, and the implications for SCSI target storage configurations. This tag is relevant for Linux system administrators, kernel developers, and IT professionals managing SCSI target deployments.
