Description Jan Lieskovsky 2011-03-29 09:49:00 EDT
Originally, the CVE-2010-4250 identifier has been assigned to the
following vulnerability:

Memory leak in the inotify_init() system call could, in some cases,
leak a group, allowing a local, unprivileged user to eventually cause
a denial of service.

Later, it was found that relevant upstream commit:
a2ae4cc9a16e211c8a128ba10d22a85431f093ab, v2.6.37-rc5

did not properly address the issue / introduced a regression
(slab corruption by double free of user_struct in inotify_init1),
which could allow a local, unprivileged user to cause a denial of
service (kernel crash).
