CVE-2014-0205

Published: 28 September 2014

The futex_wait function in kernel/futex.c in the Linux kernel before 2.6.37 does not properly maintain a certain reference count during requeue operations, which allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that triggers a zero count.

From the Ubuntu security team

Louis Rilling and Matthieu Fertré reported a use after free error in the Linux kernel's futex_wait function. A local user could exploit this flaw to cause a denial of service (system crash) or possibly gain privileges via a specially crafted application.
