Descriptions
Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing.
Una condición de carrera en fs/timerfd.c en el kernel Linux en versiones anteriores a la 4.10.15 permite que usuarios locales obtengan privilegios o provoquen una denegación de servicio (corrupción de lista o use-after-free) mediante operaciones simultáneas de descriptor de archivo que aprovechan la cola inadecuada might_cancel.
A race condition was found in the Linux kernel before version 4.11-rc1 in 'fs/timerfd.c' file which allows a local user to cause a kernel list corruption or use-after-free via simultaneous operations with a file descriptor which leverage improper 'might_cancel' queuing. An unprivileged local user could use this flaw to cause a denial of service of the system. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
