CVE-2011-1082: Linux Kernel

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

fs/eventpoll.c in the Linux kernel before 2.6.38 places epoll file descriptors within other epoll data structures without properly checking for (1) closed loops or (2) deep chains, which allows local users to cause a denial of service (deadlock or stack memory consumption) via a crafted application that makes epoll_create and epoll_ctl system calls.

Affected products

• Linux Linux Kernel: before 2.6.38 (fixed in 2.6.38)
