Descriptions

fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23 does not properly zero out the dio struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio test.

fs/direct-io.c del subsistema dio del núcleo de Linux anterior a 2.6.23, no suprime de forma correcta la estructura dio, esto permite a usuario locales provocar una denegación de servicio (OOPS), como se ha demostrado en determinados test fio.

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel. The issues include insecure misconfigurations, an integer overflow, and more.
