About this tag
CVE-2026-23292 is a Linux kernel vulnerability involving a recursive locking issue in the configfs subsystem, specifically within the SCSI target core. The bug occurs in __configfs_open_file() when target_core_item_dbroot_store() reopens a configfs path while already holding frag_sem, creating a self-referential lock acquisition path that risks deadlock. The fix replaces filp_open() with kern_path() to avoid this recursive locking. While the vulnerability is narrow in scope, it affects core kernel synchronization machinery, making it relevant for Linux system administrators and developers managing kernel security updates.

    CVE-2026-23292: Fixing Recursive Locking in Linux configfs SCSI Target

    The Linux kernel’s CVE-2026-23292 is a classic example of a bug that looks narrow on paper but matters because it sits in the kernel’s core synchronization machinery. The issue was assigned after maintainers fixed a recursive locking problem in __configfs_open_file(), where...
