https://notcve.org/view.php?id=CVE-2014-3646
arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through 3.17.2 does not have an exit handler for the INVVPID instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. arch/x86/kvm/vmx.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 no tiene un manejador de salida para la instrucción INVVPID, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo invitado) a través de una aplicación manipulada. It was found that the Linux kernel's KVM subsystem did not handle the VM exits gracefully for the invvpid (Invalidate Translations Based on VPID) instructions. On hosts with an Intel processor and invppid VM exit support, an unprivileged guest user could use these instructions to crash the guest. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a642fc305053cc1c6e47e4f4df327895747ab485 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://rhn.redhat.com/errata/RHSA-2015-0126.html http://rhn.redhat.com/errata/RHSA-2015-0284.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http://www. • CWE-248: Uncaught Exception •

Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users to cause a denial of service (host OS crash) by leveraging incorrect PIT emulation. Condición de carrera en la función __kvm_migrate_pit_timer en arch/x86/kvm/i8254.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo anfitrión) mediante el aprovechamiento de la emulación PIT incorrecta. A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=2febc839133280d5a5e8e1179c94ea674489dae2 http://rhn.redhat.com/errata/RHSA-2015-0126.html http://rhn.redhat.com/errata/RHSA-2015-0284.html http://rhn.redhat.com/errata/RHSA-2015-0869.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http://www.ubuntu.com/usn/USN-2394-1 http://www.ubuntu.com/usn/USN-2417-1 http://www.ubun • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2014-7283
The xfs_da3_fixhashpath function in fs/xfs/xfs_da_btree.c in the xfs implementation in the Linux kernel before 3.14.2 does not properly compare btree hash values, which allows local users to cause a denial of service (filesystem corruption, and OOPS or panic) via operations on directories that have hash collisions, as demonstrated by rmdir operations. La función xfs_da3_fixhashpath en fs/xfs/xfs_da_btree.c en la implementación xfs en el kernel de Linux anterior a 3.14.2 no compara debidamente los valores de hashes btree, lo que permite a usuarios locales causar una denegación de servicio (corrupción del sistema de ficheros y OOPS o pánico) a través de operaciones sobre directorios que tienen colisiones de hashes, tal y como fue demostrado por operaciones rmdir. A denial of service flaw was found in the way the Linux kernel's XFS file system implementation ordered directory hashes under certain conditions. A local attacker could use this flaw to corrupt the file system by creating directories with colliding hash values, potentially resulting in a system crash. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c88547a8119e3b581318ab65e9b72f27f23e641d http://marc.info/?l=linux-xfs&m=139590613002926&w=2 http://rhn.redhat.com/errata/RHSA-2014-1943.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.14.2 http://www.openwall.com/lists/oss-security/2014/10/01/29 http://www.securityfocus.com/bid/70261 https://bugzilla.redhat.com/show_bug.cgi?id=1148777 https://github.com/torvalds/linux/co • CWE-399: Resource Management Errors •

https://notcve.org/view.php?id=CVE-2014-7145
The SMB2_tcon function in fs/cifs/smb2pdu.c in the Linux kernel before 3.16.3 allows remote CIFS servers to cause a denial of service (NULL pointer dereference and client system crash) or possibly have unspecified other impact by deleting the IPC$ share during resolution of DFS referrals. La función SMB2_tcon en fs/cifs/smb2pdu.c en el kernel de Linux anterior a 3.16.3 permite a servidores remotos CIFS causar una denegación de servicio (referencia a puntero nulo y caída del sistema cliente) o posiblemente tener otro impacto no especificado mediante la eliminación de el compartido IPC$ durante la resolución de las referencias DFS. A NULL pointer dereference flaw was found in the way the Linux kernel's Common Internet File System (CIFS) implementation handled mounting of file system shares. A remote attacker could use this flaw to crash a client system that would mount a file system share from a malicious server. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=18f39e7be0121317550d03e267e3ebd4dbfbb3ce http://rhn.redhat.com/errata/RHSA-2015-0102.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.3 http://www.openwall.com/lists/oss-security/2014/09/22/4 http://www.securityfocus.com/bid/69867 http://www.ubuntu.com/usn/USN-2394-1 https://github.com/torvalds/linux/commit/18f39e7be0121317550d03e267e3ebd4dbfbb3ce https://access.redhat.com/security/cve& • CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •

The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction. La función sctp_assoc_update en net/sctp/associola.c en el kernel de Linux hasta 3.15.8, cuando la autenticación SCTP está habilitada, permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo y OOPS) mediante el inicio del establecimiento de una asociación entre dos endpoints inmediatamente después de un intercambio de fragmentos INIT y INIT ACK para establecer una asociación anterior entre estos endpoints en la dirección opuesta. A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts.
