CVE-2011-1083: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

• Red Hat Enterprise Linux Desktop: version 6.0 only
• Red Hat Enterprise Linux Server: version 6.0 only
• Red Hat Enterprise Linux Workstation: version 6.0 only
