CVE-2008-5029

CVE Details

Release Date:	2008-11-10
Impact:	Important	What is this?

Description

The __scm_destroy function in net/core/scm.c in the Linux kernel 2.6.27.4, 2.6.26, and earlier makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors. Linux kernel 2.6.28 allows local users to cause a denial of service (soft lockup and process loss) via a large number of sendmsg function calls, which does not block during AF_UNIX garbage collection and triggers an OOM condition, a different vulnerability than CVE-2008-5029.
