    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...
