ufs

About this tag
The ufs tag on WindowsForum.com covers discussions about Universal Flash Storage (UFS) driver issues in the Linux kernel, including fixes for hangs, over-current protection trips, SRCU races during probe, and memory leaks. These threads detail specific CVEs and patches that address availability and stability concerns for systems using UFS host controllers, particularly on Qualcomm platforms and ARM-based devices. The content is technical, focusing on kernel-level changes, SCSI error handling, and platform driver lifecycle management. While the tag is Linux-centric, it may interest IT professionals and developers managing storage subsystems on Linux-based systems.

    Linux UFS Hang Fix CVE-2025-38119: Stable Patch for Availability

    The Linux kernel received a targeted, low‑level fix addressing a hang in the UFS (Universal Flash Storage) SCSI error handler — a bug that can cause sustained or persistent loss of availability by deadlocking kernel threads during device error recovery. The change is small and surgical at the...

    CVE-2025-68236: Linux Kernel UFS OCP Fix Adds 10ms Delay After HWRST for Qualcomm

    The Linux kernel record for CVE-2025-68236 documents a narrow but important UFS (Universal Flash Storage) driver fix that prevents an over‑current protection (OCP) trip during UFS power‑down sequences by inserting a short, defensive delay after asserting hardware reset — a change that reduces...

    CVE-2025-68224: Guarding SCSI tagset init to fix SRCU race during UFS probe

    A small change in the kernel’s block‑layer iterator code has produced an outsized operational headache: CVE‑2025‑68224 fixes a regression where a call to scsi_host_busy can race against tagset initialization, causing kernel stack traces during device probe and potentially blocking UFS platform...

    Linux UFS Platform Driver Fix CVE-2024-57872: Prevent Memory Leaks

    A subtle lifecycle bug in the Linux UFS platform driver — tracked as CVE-2024-57872 — can leave a host bus adapter (HBA) detached code path improperly cleaned up during ufshcd_pltfrm_remove, producing memory leaks and an availability risk for affected systems. The fix upstream ensures the SCSI...
