CVE-2017-6874

Priority
Description
Race condition in kernel/ucount.c in the Linux kernel through 4.10.2 allows
local users to cause a denial of service (use-after-free and system crash)
or possibly have unspecified other impact via crafted system calls that
leverage certain decrement behavior that causes incorrect interaction
between put_ucounts and get_ucounts.
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.10 and earlier preview kernels
linux-lts-saucy no longer receives official support
