CVE-2014-9090
Publication date 29 November 2014
Last updated 24 July 2024
Ubuntu priority
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.
From the Ubuntu Security Team
Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack Segment (SS) register on the x86 architecture. A local attacker could exploit this flaw to cause a denial of service (panic).
