https://notcve.org/view.php?id=CVE-2009-2695
The Linux kernel before 2.6.31-rc7 does not properly prevent mmap operations that target page zero and other low memory addresses, which allows local users to gain privileges by exploiting NULL pointer dereference vulnerabilities, related to (1) the default configuration of the allow_unconfined_mmap_low boolean in SELinux on Red Hat Enterprise Linux (RHEL) 5, (2) an error that causes allow_unconfined_mmap_low to be ignored in the unconfined_t domain, (3) lack of a requirement for the CAP_SYS_RAWIO capability for these mmap operations, and (4) interaction between the mmap_min_addr protection mechanism and certain application programs. El kernel de Linux antes de v2.6.31-rc7 no previene debidamente las operaciones nmap que apuntan a una pagina cero y otras direcciones de memoria bajas, lo que permite a usuarios locales obtener privilegios mediante la explotación de vulnerabilidades de desreferencia a puntero NULL, relacionados con (1) la configuración por defecto del boolano allow_unconfined_mmap_low en SELinux en Red Hat Enterprise Linux (RHEL) 5, (2) un error que provoca allow_unconfined_mmap_low para ser ignorado en el dominio unconfined_t, (3) la falta de un requisito de la capacidad CAP_SYS_RAWIO para estas nmap operaciones, y (4) la interacción entre el mecanismo de protección mmap_min_addr y algunos programas de aplicación. • http://danwalsh.livejournal.com/30084.html http://eparis.livejournal.com/606.html http://git.kernel.org/?p=linux/kernel/git/jmorris/security-testing-2.6.git%3Ba=commit%3Bh=47d439e9fb8a81a90022cfa785bf1c36c4e2aff6 http://git.kernel.org/?p=linux/kernel/git/jmorris/security-testing-2.6.git%3Ba=commit%3Bh=7c73875e7dda627040b12c19b01db634fa7f0fd1 http://git.kernel.org/?p=linux/kernel/git/jmorris/security-testing-2.6.git%3Ba=commit%3Bh=84336d1a77ccd2c06a730ddd38e695c2324a7386 http://git.kernel.org/?p=linux/kernel/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2009-2849
The md driver (drivers/md/md.c) in the Linux kernel before 2.6.30.2 might allow local users to cause a denial of service (NULL pointer dereference) via vectors related to "suspend_* sysfs attributes" and the (1) suspend_lo_store or (2) suspend_hi_store functions. NOTE: this is only a vulnerability when sysfs is writable by an attacker. El driver md (drivers/md/md.c) en el kernel de Linux anteriores a 2.6.30.2 podría permitir a usuarios locales producir una denegación de servicio (referencia a un puntero nulo) a través de vectores relacionados con los " atributos suspend*sysfs" a la funciones (1) suspend_lo_store o (2) suspend_hi_store.
