  "message": "ipc: sysvsem: force unshare(CLONE_SYSVSEM) when CLONE_NEWIPC\n\nsys_unshare(CLONE_NEWIPC) doesn\u0027t handle the undo lists properly, this can\ncause a kernel memory corruption.  CLONE_NEWIPC must detach from the existing\nundo lists.\n\nFix, part 2: perform an implicit CLONE_SYSVSEM in CLONE_NEWIPC.  CLONE_NEWIPC\ncreates a new IPC namespace, the task cannot access the existing semaphore\narrays after the unshare syscall.  Thus the task can/must detach from the\nexisting undo list entries, too.\n\nThis fixes the kernel corruption, because it makes it impossible that\nundo records from two different namespaces are in sysvsem.undo_list.\n\nSigned-off-by: Manfred Spraul \u003cmanfred@colorfullife.com\u003e\nSigned-off-by: Serge E.
