CVE-2026-14367 I3C IBI work-node free-list data race between ISR and workqueue thread

The I3C IBI subsystem in drivers/i3c/i3cibiworkq.c hands out statically-allocated work nodes through a free-list i3cibiworknodesfree implemented as a plain sysslistt, which provides no synchronization. The allocation helpers i3cibiworkenqueue, i3cibiworkenqueuetargetirq, i3cibiworkenqueuehotjoin,...

CVE-2026-14367

CVE-2026-14367 affects the Zephyr RTOS I3C IBI subsystem in drivers/i3c/i3c_ibi_workq.c. A statically-allocated work-node free-list (sys_slist_t) is accessed without synchronization: ISR-context callers invoke sys_slist_get() while the workqueue thread calls sys_slist_append(). This data race can...
