CVE-2016-6136 – kernel: Race condition vulnerability in execve argv arguments

https://notcve.org/view.php?id=CVE-2016-6136

Race condition in the audit_log_single_execve_arg function in kernel/auditsc.c in the Linux kernel through 4.7 allows local users to bypass intended character-set restrictions or disrupt system-call auditing by changing a certain string, aka a "double fetch" vulnerability. Condición de carrera en la función audit_log_single_execve_arg en kernel/auditsc.c en el kernel de Linux hasta la versión 4.7 permite a usuarios locales eludir restricciones de set de caracteres intencionados o interrumpir la auditoria del sistema de llamada cambiando una cierta cadena, también conocido como una vulnerabilidad de "doble recuperación". When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=43761473c254b45883a64441dd0bc85a42f3645c http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://rhn.redhat.com/errata/RHSA-2017-0307.html http://www.securityfocus.com/archive/1/538835/30/0/threaded http://www.securityfocus.com/bid/91558 https://bugzilla.kernel.org/show_bug.cgi?id=120681 https://bugzilla.redhat.com/show_bug.cgi?id=1353533 https://github • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2016-6156

https://notcve.org/view.php?id=CVE-2016-6156

Race condition in the ec_device_ioctl_xcmd function in drivers/platform/chrome/cros_ec_dev.c in the Linux kernel before 4.7 allows local users to cause a denial of service (out-of-bounds array access) by changing a certain size value, aka a "double fetch" vulnerability. Condición de carrera en la función ec_device_ioctl_xcmd en drivers/platform/chrome/cros_ec_dev.c en el kernel de Linux en versiones anteriores a 4.7 permite a usuarios locales provocar una denegación de servicio (acceso al array fuera de rango) cambiando un cierto valor de tamaño, también conocido como una vulnerabilidad de "doble recuperación". • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=096cdc6f52225835ff503f987a0d68ef770bb78e http://seclists.org/bugtraq/2016/Jul/20 http://www.securityfocus.com/bid/91553 https://bugzilla.kernel.org/show_bug.cgi?id=120131 https://bugzilla.redhat.com/show_bug.cgi?id=1353490 https://github.com/torvalds/linux/commit/096cdc6f52225835ff503f987a0d68ef770bb78e • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel before 4.6 allows local users to obtain sensitive information from kernel memory by changing a certain length value, aka a "double fetch" vulnerability. Condición de carrera en la función sclp_ctl_ioctl_sccb en drivers/s390/char/sclp_ctl.c en el kernel de Linux en versiones anteriores a 4.6 permite a usuarios locales obtener información sensible de la memoria del kernel cambiando un valor de longitud determinado, también conocida como una vulnerabilidad "double fetch". • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=532c34b5fbf1687df63b3fcd5b2846312ac943c6 http://www.debian.org/security/2016/dsa-3616 http://www.securityfocus.com/archive/1/538803/30/0/threaded http://www.securityfocus.com/bid/91540 https://bugzilla.kernel.org/show_bug.cgi?id=116741 https://github.com/torvalds/linux/commit/532c34b5fbf1687df63b3fcd5b2846312ac943c6 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2016-3070 – kernel: Null pointer dereference in trace_writeback_dirty_page()

https://notcve.org/view.php?id=CVE-2016-3070

The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move. La implementación trace_writeback_dirty_page en include/trace/events/writeback.h en el kernel de Linux en versiones anteriores a 4.4 interactúa incorrectamente con mm/migrate.c, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y caída de sistema) o posiblemente tener otro impacto no especificado desencadenando un cierto movimiento de página. A security flaw was found in the Linux kernel that an attempt to move page mapped by AIO ring buffer to the other node triggers NULL pointer dereference at trace_writeback_dirty_page(), because aio_fs_backing_dev_info.dev is 0. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=42cb14b110a5698ccf26ce59c4441722605a3743 http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2016/dsa-3607 http://www.securityfocus.com/bid/90518 http://www.ubuntu.com/usn/USN-3034-1 http://www.ubuntu.com/usn/USN-3034-2 http://www.ubuntu.com/usn/USN-3035-1 http://www.ubuntu.com/usn/USN-3035-2 http://www • CWE-476: NULL Pointer Dereference •
