  "details" : [ "The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.", "A flaw was found in the Linux kernel where the coredump implementation does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs. This allows local users to obtain sensitive information, cause a denial of service (DoS), or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls." ],
