Vulnerability Name:

CVE-2014-0205 (CCN-95879)

Assigned:2013-12-03
Published:2014-09-09
Updated:2023-02-13
Summary: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.
