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...
