CVE-2010-4162: Integer Overflow
First published: Fri Nov 12 2010(Updated: )
Due to integer underflow and overflow issues when determining the number of pages required for maliciously crafted I/O requests, a local user could send a device ioctl that results in the sequential allocation of a very large number of pages, causing the OOM killer to be invoked and crashing the system: Proposed patch: <a href="http://git.kernel.org/?p=linux/kernel/git/axboe/linux-2.6-block.git;a=commit;h=cb4644cac4a2797afc847e6c92736664d4b0ea34">http://git.kernel.org/?p=linux/kernel/git/axboe/linux-2.6-block.git;a=commit;h=cb4644cac4a2797afc847e6c92736664d4b0ea34</a> Acknowledgements: Red Hat would like to thank Dan Rosenberg for reporting this issue.
