CVE-2012-2390

Memoria no liberada (memory leak) en mm/hugetlb.c del kernel de Linux en versiones anteriores a la 3.4.2. Permite a usuarios locales provocar una denegación de servicio (consumo de la memoria o caída del sistema) a traves de operaciones mmap MAP_HUGETLB inválidas.

The kernel packages contain the Linux kernel, the core of any Linux operating system. An integer overflow flaw was found in the i915_gem_do_execbuffer() function in the Intel i915 driver in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service. This issue only affected 32-bit systems. A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap() failure path when the MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to cause a denial of service.
