CVE-2026-43439
In the Linux kernel, the following vulnerability has been resolved: cgroup: fix race between task migration and iteration When a task is migrated out of a cssset, cgroupmigrateaddtask first moves it from cset-tasks to cset-mgtasks via: listmovetail&task-cglist, &cset-mgtasks; If a csstaskiter...
UBUNTU-CVE-2026-43418
In the Linux kernel, the following vulnerability has been resolved: sched/mmcid: Prevent CID stalls due to concurrent forks A newly forked task is accounted as MMCID user before the task is visible in the process' thread list and the global task list. This creates the following problem: CPU1 CPU2...

CVE-2026-43439
CVE-2026-43439 : In the Linux kernel, a race between task migration and iteration in cgroup can cause iterators to skip tasks when a task migrates from cset->tasks to cset->mg_tasks. The patch adds a call to css_set_skip_task_iters() before unlinking the task from cset->tasks, advancing ...

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...
