The epoll_ctl system call in fs/eventpoll.c in the Linux kernel before 3.2.24 does not properly handle ELOOP errors in EPOLL_CTL_ADD operations, which allows local users to cause a denial of service (file-descriptor consumption and system crash) via a crafted application that attempts to create a circular epoll dependency. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1083.

Security readout for executives and security teams

This is a local Linux kernel denial-of-service issue. A user or process already able to run code on a host could trigger faulty epoll handling and consume file descriptors, potentially crashing the system. It is not described as remotely exploitable in the provided sources. Exposure is most relevant to legacy Linux systems or vendor appliances running kernels before 3.2.24 or missing the vendor backport. Risk is higher on shared systems, hosting platforms, or servers where untrusted local users or workloads can execute code. Treat this as a legacy local availability risk, not an internet-edge emergency. Patch or retire affected kernels during normal vulnerability remediation, with faster handling for shared or multi-tenant systems where local code execution by untrusted users is plausible. Mitigation focus: Update affected Linux kernels to a fixed vendor-supported release.; Confirm vendor backports for older supported distributions or appliances.; Prioritize shared hosts with untrusted local users or workloads..
