CVE-2010-4250

Published: 12 January 2012

Memory leak in the inotify_init1 function in fs/notify/inotify/inotify_user.c in the Linux kernel before 2.6.37 allows local users to cause a denial of service (memory consumption) via vectors involving failed attempts to create files.

From the Ubuntu Security Team

Vegard Nossum discovered a leak in the kernel's inotify_init() system call. A local, unprivileged user could exploit this to cause a denial of service.
