CVE-2026-43418

CVE-2026-43418 describes a race in the Linux kernel sched/mmcid subsystem: when new tasks are created concurrently, a newly forked task is counted as an MMCID user before it is visible in thread and task lists, which can lead to an incorrect CID allocation and potentially a machine stall. The mit...

CVE-2026-43417

CVE-2026-43417 affects the Linux kernel, specifically the vfork()/CLONE_VM handling in sched/mmcid. The bug occurs when the number of tasks in a process is smaller than MMCID users, causing the system to loop through the task list and double-count already processed tasks. If this double processin...
