SuSE 11.2 Security Update : Linux kernel (SAT Patch Numbers 6163 / 6164 / 6172)

The SUSE Linux Enterprise 11 SP2 kernel has been updated to 3.0.26, which fixes a lot of bugs and security issues. The following security issues have been fixed : - A locking problem in transparent hugepage support could be used by local attackers to potentially crash the host, or via kvm a...

kernel: excessive in kernel CPU consumption when creating large nested epoll structures

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 epollcreate and epollctl system calls...

CVE-2011-1083

The CVE-2011-1083 issue affects the Linux kernel epoll implementation (epoll_ctl/epoll_create) as shipped in 2.6.37.2 and earlier. Local attackers can cause CPU denial of service by crafting a user-space application that creates and manages epoll file descriptors, exploiting improper traversal of...
