https://notcve.org/view.php?id=CVE-2012-3375
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. La llamada al sistema epoll_ctl en fs/eventpoll.c en el Kernel de Linux anteriores a v3.2.24 no gestiona de forma adecuada errores ELOOP en operaciones EPOLL_CTL_ADD, lo que permite a usuarios locales provocar una denegación de servicio (consumo de descriptores de ficheros y caída del sistema) a través de una aplicación manipulada que intenta crear una dependencia epoll circular. NOTA: esta vulnerabilidad existe debido a una resolución incorrecta de CVE-2011-1083.
