Linux kernel の epoll 実装におけるサービス運用妨害 (DoS) の脆弱性

Title	Linux kernel の epoll 実装におけるサービス運用妨害 (DoS) の脆弱性
Summary	Linux kernel の epoll 実装は、epoll ファイル記述子のツリーを適切に移動しないため、サービス運用妨害 (CPU消費) 状態となる脆弱性が存在します。
Possible impacts	ローカルユーザにより、epoll_create および epoll_ctl システムコールを発生させる巧妙に細工されたアプリケーションを介して、サービス運用妨害 (CPU消費) 状態にされる可能性があります。
Solution	ベンダ情報および参考情報を参照して適切な対策を実施してください。

NVD Vulnerability Information

CVE-2011-1083

Summary	The epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service (CPU consumption) via a crafted application that makes epoll_create and epoll_ctl system calls.
