The do_mmap_pgoff function in mm/nommu.c in the Linux kernel before 2.6.31.6, when the CPU lacks a memory management unit, allows local users to cause a denial of service (OOPS) via an application that attempts to allocate a large amount of memory. La función do_mmap_pgoff en mm/nommu.c en el kernel de Linux anteriores a v2.6.31.6, cuando la CPU carece de unidad de gestión de memori, permite a usuarios locales provocar una denegación de servicio (OOPS) mediante una aplicación que intente reservar una gran cantidad de memoria. • https://www.exploit-db.com/exploits/10017 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=89a8640279f8bb78aaf778d1fc5c4a6778f18064 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.31.6 http://www.openwall.com/lists/oss-security/2009/11/09/2 http://www.openwall.com/lists/oss-security/2009/11/13/3 http://www.ubuntu.com/usn/usn-864-1 • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2009-3726
The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. La función nfs4_proc_lock en fs/nfs/nfs4proc.c en el cliente NFSv4 en el Kernel de Linux anteriores a v2.6.31-rc4 permite a servidores NFS remotos provocar una denegación de servicio (desreferenciación de puntero NULL y pánico) si se envía cierta respuesta conteniendo atributos de fichero no correctos, lo que provoca un intento de uso de un fichero abierto que carece de un estado NFSv4. • https://www.exploit-db.com/exploits/10202 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=d953126a28f97ec965d23c69fd5795854c048f30 http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00007.html 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.vmware.com/pipermail/security-ann • CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •

The connector layer in the Linux kernel before 2.6.31.5 does not require the CAP_SYS_ADMIN capability for certain interaction with the (1) uvesafb, (2) pohmelfs, (3) dst, or (4) dm subsystem, which allows local users to bypass intended access restrictions and gain privileges via calls to functions in these subsystems.

The get_instantiation_keyring function in security/keys/keyctl.c in the KEYS subsystem in the Linux kernel before 2.6.32-rc5 does not properly maintain the reference count of a keyring, which allows local users to gain privileges or cause a denial of service (OOPS) via vectors involving calls to this function without specifying a keyring by ID, as demonstrated by a series of keyctl request2 and keyctl list commands. La función get_instantiation_keyring de security/keys/keyctl.c en el subsistema KEYS del kernel de Linux en versiones anteriores a la v2.6.32-rc5 no mantiene apropiadamente la cuenta de referencias de un "keyring", lo que permite a usuarios locales obtener privilegios o provocar una denegación de servicio (OOPS) a través de vectores de ataque que involucran llamadas a esta función sin especificar un "keyring" por ID, como se ha demostrado por series de "keyctl request2" y comandos "keyctl list". • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=21279cfa107af07ef985539ac0de2152b9cba5f5 http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00000.html http://marc.info/?l=oss-security&m=125619420905341&w=2 http://marc.info/?l=oss-security&m=125624091417161&w=2 http://secunia.com/advisories/37086 http://secunia.com/advisories/38017 http://twitter.com/spendergrsec/statuses/4916661870 http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeL • CWE-310: Cryptographic Issues •
