CVSS: 6.2EPSS: 0%CPEs: 11EXPL: 1CVE-2010-4258 – Linux Kernel 2.6.37 (RedHat / Ubuntu 10.04) - 'Full-Nelson.c' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2010-4258
The do_exit function in kernel/exit.c in the Linux kernel before 2.6.36.2 does not properly handle a KERNEL_DS get_fs value, which allows local users to bypass intended access_ok restrictions, overwrite arbitrary kernel memory locations, and gain privileges by leveraging a (1) BUG, (2) NULL pointer dereference, or (3) page fault, as demonstrated by vectors involving the clear_child_tid feature and the splice system call. La función do_exit en kernel/exit.c en el kernel de Linux anteriores a v2.6.36.2 no gestiona de forma adecuada el KERNEL_DS y el valor get_fs, lo que permite a usuarios locales saltarse las restricciones access_ok, sobrescribiendo posiciones de memoria del kernel, y obtener privilegios mediante el aprovechamiento de un (1) ERROR, (2) desreferencia a un puntero NULL, o (3) error de página, como lo demuestró por vectores que implican la característica clear_child_tid en las llamadas al sistema de unión. • https://www.exploit-db.com/exploits/15704 http://archives.neohapsis.com/archives/fulldisclosure/2010-12/0086.html http://blog.nelhage.com/2010/12/cve-2010-4258-from-dos-to-privesc http://code.google.com/p/chromium-os/issues/detail?id=10234 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=33dd94ae1ccbfb7bf0fb6c692bc3d1c4269e6177 http://googlechromereleases.blogspot.com/2011/01/chrome-os-beta-channel-update.html http://lists.fedoraproject.org/pipermail/package-annou • CWE-269: Improper Privilege Management •

The io_submit_one function in fs/aio.c in the Linux kernel before 2.6.23 allows local users to cause a denial of service (NULL pointer dereference) via a crafted io_submit system call with an IOCB_FLAG_RESFD flag. La función io_submit_one en fs/aio.c del kernel de Linux en versiones anteriores a la 2.6.23 permite a usuarios locales provocar una denegación de servicio (resolución de referencia de puntero NULL) a través de una llamada del sistema io_submit modificada con el flag IOCB_FLAG_RESFD. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=87e2831c3fa39cbf6f7ab676bb5aef039b9659e2 http://secunia.com/advisories/46397 http://securitytracker.com/id?1024708 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.23 http://www.redhat.com/support/errata/RHSA-2010-0839.html http://www.securityfocus.com/archive/1/520102/100/0/threaded http://www.vmware.com/security/advisories/VMSA-2011-0012.html https://bugzilla.redhat.com/show_bug.cgi?id •

The snd_hdspm_hwdep_ioctl function in sound/pci/rme9652/hdspm.c in the Linux kernel before 2.6.36-rc6 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via an SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl call.
