A flaw was found in the way the Linux kernel handled exceptions delivered
after a stack switch operation via Mov SS or Pop SS instructions. During
the stack switch operation, processor does not deliver interrupts and
exceptions, they are delivered once the first instruction after the stack
switch is executed. An unprivileged system user could use this flaw to
crash the system kernel resulting in DoS. This CVE-2018-10872 was assigned
due to regression of CVE-2018-8897 in Red Hat Enterprise Linux 6.10 GA
kernel. No other versions are affected by this CVE.
