REDHAT-BUG-369531

First published: Wed Nov 07 2007(Updated: )

Description of problem: The blkif_get_x86_32_req() and blkif_get_x86_64_req() functions don't sanity-check the req->nr_segments value. The functions are part of the 32-on-64 support. They translate block I/O request structs from 32bit ABI to 64bit ABI and visa versa. They are used in case 32bit paravirtualized guests (or 32bit hvm guests with pv-on-hvm drivers installed) are running on a 64bit host. Version-Release number of selected component (if applicable): RHEL 5.1 kernel.
