CVE-2026-43417

In the Linux kernel, the following vulnerability has been resolved: sched/mmcid: Handle vfork/CLONEVM correctly Matthieu and Jiri reported stalls where a task endlessly loops in mmgetcid when scheduling in. It turned out that the logic which handles vfork'ed tasks is broken. It is invoked when th...

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...
