CVSS 3.1
7.0 highCVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2019-11599
High (7.0) in linux linux kernel. EPSS 1.0% chance of exploitation in the next 30 days.
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.
