CVE-2010-3904: Linux Kernel Improper Input Validation Vulnerability
First published: Thu Oct 14 2010(Updated: )
Description of problem: The handling functions for sending and receiving messages, in rds_page_copy_user(), use the unchecked __copy_*_user_inatomic functions without any access checks on user-provided pointers. As a result, by passing a kernel address as an iovec base address in recvmsg-style calls, a local user can overwrite arbitrary kernel memory, which can easily be used to escalate privileges to root. Introduced via 7875e18e (v2.6.30-rc1). Acknowledgements: Red Hat would like to thank Dan Rosenberg of Virtual Security Research for reporting this issue.
