A vulnerability was found in Linux Kernel 2.6.16.59 (Operating System). It has been classified as critical. Affected is an unknown part. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The inotify functionality in Linux kernel 2.6 before 2.6.28-rc5 might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount.

The bug was discovered 11/15/2008. The weakness was disclosed 11/20/2008 by Al Viro (Website). The advisory is shared for download at redhat.com. This vulnerability is traded as CVE-2008-5182 since 11/20/2008. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 976 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 35036 (Debian DSA-1681-1 : linux-2.6.24 - denial of service/privilege escalation), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165629 (SUSE Enterprise Linux Security Update for Kernel (SUSE-SA:2009:008)).
