CVE-2011-4621

El kernel de Linux antes de v2.6.37 no aplica la optimización de una actualización de reloj, lo que permite a usuarios locales provocar una denegación de servicio (bloqueo del sistema) a través de una aplicación que ejecuta código en un bucle.

Aristide Fattori and Roberto Paleari reported a flaw in the Linux kernel's handling of IPv4 icmp packets. A remote user could exploit this to cause a denial of service. Vegard Nossum discovered a leak in the kernel's inotify_init() system call. A local, unprivileged user could exploit this to cause a denial of service. An error was discovered in the kernel's handling of CUSE (Character device in Userspace). A local attacker might exploit this flaw to escalate privilege, if access to /dev/cuse has been modified to allow non-root users. Various other issues were also addressed.
