CVE-2010-4346 Open this link in a new tabHow to fix?
Upgrade Oracle:5 kernel-uek-debug to version 0:2.6.32-100.28.11.el5 or higher.
This issue was patched in ELSA-2011-2014.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug package and not the kernel-uek-debug package as distributed by Oracle.
See How to fix? for Oracle:5 relevant fixed versions and status.
The install_special_mapping function in mm/mmap.c in the Linux kernel before 2.6.37-rc6 does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application.
