CVE-2009-3620 – kernel: r128 IOCTL NULL pointer dereferences when CCE state is uninitialised

https://notcve.org/view.php?id=CVE-2009-3620

The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. El controlador ATI Rage 128 (también conocido como r128), en el Kernel de Linux anterior a v2.6.31-git11 no verifica de forma adecuada el estado de inicialización del "Concurrent Command Engine (CCE)", lo que permite a usuarios locales provocar una denegación de servicio (desreferenciación de puntero nulo y caída del sistema) o posiblemente obtener privilegios a través de llamadas ioctl sin especificar. • http://article.gmane.org/gmane.linux.kernel/892259 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7dc482dfeeeefcfd000d4271c4626937406756d7 http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00007.html http://lists.vmware.com/pipermail/sec • CWE-476: NULL Pointer Dereference CWE-908: Use of Uninitialized Resource •
