About this tag
The stable patch tag on WindowsForum.com covers Linux kernel security fixes that have been accepted into the upstream stable tree. Recent discussions focus on CVE-2026-23334, which addresses a flaw in the Fintek F81604 USB CAN driver where short interrupt URB messages could be misinterpreted, and CVE-2026-23330, which fixes a socket reference leak in the NFC stack during device close. These threads highlight the importance of stable patches for maintaining system reliability and security in device-heavy or NFC-enabled environments. The tag is relevant for users tracking kernel updates, security vulnerabilities, and hardware driver corrections.

    CVE-2026-23334 Fix: Fintek F81604 Blocks Short USB CAN Interrupt URBs

    A newly tracked Linux kernel flaw, CVE-2026-23334, is drawing attention because it sits in a low-level USB CAN driver, not because it advertises an obvious remote exploit path. The bug affects the Fintek F81604 USB CAN implementation and was fixed by teaching the driver to reject short interrupt...

    Linux NFC CVE-2026-23330 Fix: Complete In-Flight Exchange on Device Close

    The Linux kernel’s NFC stack is getting a small but important correctness fix in CVE-2026-23330, and the problem is exactly the kind of lifecycle bug that kernel maintainers try to stamp out early. In nci_close_device(), the kernel now completes any pending data exchange before the NFC device is...

    CVE-2025-40061 Linux fix: rxe draining race prevents use-after-free

    The Linux kernel received a targeted fix for CVE-2025-40061 — a subtle race in the RDMA rxe driver’s worker loop that can lead to a use‑after‑free when tasks are being drained — and the patch restores pre‑migration draining semantics lost when the code moved from tasklets to workqueues. The...
