The oz_usb_handle_ep_data function in drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (divide-by-zero error and system crash) via a crafted packet. La función oz_usb_handle_ep_data en drivers/staging/ozwpan/ozusbsvc1.c en el controlador OZWPAN en el kernel de Linux hasta 4.0.5 permite a atacantes remotos causar una denegación de servicio (un error de dividir por cero y caída de sistema) a través de un paquete manipulado. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=04bf464a5dfd9ade0dda918e44366c2c61fce80b http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http://openwall.com/lists/oss-security/2015/06/05/7 http://www.securityfocus.com/bid/74668 http://www.ubuntu.com/usn/USN-2665-1 http://www.ubuntu.com/usn/USN-2667-1 https://github.com/torvalds/linux/commit/04bf464a5dfd9ade0dda918e44366c2c61fce80b • CWE-189: Numeric Errors •
CVSS: 7.2EPSS: 0%CPEs: 6EXPL: 2CVE-2015-1805 – kernel: pipe: iovec overrun leading to memory corruption
https://notcve.org/view.php?id=CVE-2015-1805
The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in the Linux kernel before 3.16 do not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an "I/O vector array overrun." Vulnerabilidad en las implementaciones (1) pipe_read y (2) pipe_write en fs/pipe.c en el kernel de Linux en versiones anteriores a 3.16, no considera correctamente los efectos secundarios de llamadas __copy_to_user_inatomic y __copy_from_user_inatomic fallidas, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) o posiblemente obtener privilegios a través de una aplicación manipulada, también conocida como una 'saturación del array del vector I/O'. It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. • https://github.com/panyu6325/CVE-2015-1805 https://github.com/ireshchaminda1/Android-Privilege-Escalation-Remote-Access-Vulnerability-CVE-2015-1805 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=637b58c2887e5e57850865839cc75f59184b23d1 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f0d1bec9d58d4c038d0ac958c9af82be6eb18045 http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00049.html • CWE-17: DEPRECATED: Code •

The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit. La implementación Btrfs en el kernel de Linux anterior a 3.19 no asegura que el estado xattr visible sea consistente con un remplazo solicitado, lo que permite a usuarios locales evadir las configuraciones ACL y ganar privilegios a través de las operaciones del sistema de ficheros estándares (1) durante una ventana de tiempo de remplazo de xattr, relacionado con una condición de carrera o (2) después de intento de remplazo de xattr que falla porque la fecha no encaja. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5f5bc6b1e2d5a6f827bc860ef2dc5b6f365d1339 http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00009.html http://www.openwall.com/lists/oss-security/2015/03/24/11 http://www.securitytracker.com/id/1032418 https://bugzilla.redhat.com/show_bug.cgi?id=1205079 https://github.com/torvalds/linux/commit/5f5bc6b1e2d5a6f827bc860ef2dc5b6f365d1339 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2015-2666
Stack-based buffer overflow in the get_matching_model_microcode function in arch/x86/kernel/cpu/microcode/intel_early.c in the Linux kernel before 4.0 allows context-dependent attackers to gain privileges by constructing a crafted microcode header and leveraging root privileges for write access to the initrd. Desbordamiento de buffer basado en pila en la función get_matching_model_microcode en arch/x86/kernel/cpu/microcode/intel_early.c en el kernel de Linux anterior a 4.0 permite a atacantes dependientes de contexto ganar privilegios mediante la construcción de una cabecera de microcódigo manipulada y el aprovechamiento de privilegios root para acceso de escritura al initrd. A stack-based buffer overflow flaw was found in the Linux kernel's early load microcode functionality. On a system with UEFI Secure Boot enabled, a local, privileged user could use this flaw to increase their privileges to the kernel (ring0) level, bypassing intended restrictions in place. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f84598bd7c851f8b0bf8cd0d7c3be0d73c432ff4 http://lists.fedoraproject.org/pipermail/package-announce/2015-March/153329.html http://rhn.redhat.com/errata/RHSA-2015-1534.html http://www.openwall.com/lists/oss-security/2015/03/20/18 http://www.securitytracker.com/id/1032414 https://bugzilla.redhat.com/show_bug.cgi?id=1204722 https://github.com/torvalds/linux/commit/f84598bd7c851f8b0bf8cd0d7c3be0d73c432ff4 https://access.redha • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2015-2830
arch/x86/kernel/entry_64.S in the Linux kernel before 3.19.2 does not prevent the TS_COMPAT flag from reaching a user-mode task, which might allow local users to bypass the seccomp or audit protection mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an attack against seccomp before 3.16. arch/x86/kernel/entry_64.S en el kernel de Linux anterior a 3.19.2 no impide que el indicador TS_COMPAT llegue a una tarea de modo de usuario, lo que podría permitir a usuarios locales evadir el mecanismo de protección de seccomp o de auditoria a través de una aplicación manipulada que utiliza la llamada de sistema (1) bifurcada o (2) cerrada, tal y como fue demostrado por un ataque sobre seccomp anterior a 3.16. A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=956421fbb74c3a6261903f3836c0740187cf038b http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00021.html http://rhn.redhat.com/errata/RHSA-2015-1137.html http://rhn.redhat.com/errata/RHSA-2015-1138.html http://rhn.redhat.com/errata/RHSA-2015-1221.html http& • CWE-264: Permissions, Privileges, and Access Controls CWE-393: Return of Wrong Status Code •
