CVE-2009-4021 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-4021): The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel before 2.6.32-rc7 might allow attackers to cause a denial of service (invalid pointer dereference and OOPS) via vectors possibly related to a memory-consumption attack. |
