https://notcve.org/view.php?id=CVE-2011-4127
The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume. El kernel de Linux anterior a v3.2.2 no restringe adecuadamente llamadas SG_IO ioctl, permitiendo a usuarios locales eludir restricciones de lectura y escritura en disco mediante el envío de un comando SCSI a (1) un dispositivo de bloques de particiones o (2) un volumen LVM. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=0bfc96cb77224736dfa35c3c555d37b3646ef35e http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ec8013beddd717d1740cfefb1a9b900deef85462 http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://secunia.com/advisories/48898 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.2 http://www& • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •

The br_parse_ip_options function in net/bridge/br_netfilter.c in the Linux kernel before 2.6.39 does not properly initialize a certain data structure, which allows remote attackers to cause a denial of service by leveraging connectivity to a network interface that uses an Ethernet bridge device. La función br_parse_ip_options en net/bridge/br_netfilter.c de los kernel Linux anteriores a v2.6.39 no inicia adecuadamente cierta estructura de datos, permitiendo que atacantes remotos provoquen denegaciones de servicio mediante la indicación de conexión a un interfaz de red que usa un dispositivo bridge Ethernet. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f8e9881c2aef1e982e5abc25c046820cd0b7cf64 http://www.openwall.com/lists/oss-security/2011/10/28/14 https://github.com/torvalds/linux/commit/f8e9881c2aef1e982e5abc25c046820cd0b7cf64 • CWE-665: Improper Initialization •
