kernel: espfix64: local DoS via do_double_fault() due to improper handling of faults associated with SS segment register

Published Nov 30, 2014 CVSS 2.0 · 4.9 Medium EPSS < 1% KEV · Not listed
Description
The do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel through 3.17.4 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to cause a denial of service (panic) via a modify_ldt system call, as demonstrated by sigreturn_32 in the linux-clock-tests test suite.
