The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access. La función ip6gre_err en net/ipv6/ip6_gre.c en el kernel de Linux permite a atacantes remotos tener impacto no especificado a través de vectores involucrando indicadores GRE flags en un paquete IPv6, que desencadenan un acceso fuera de los límites. • http://www.debian.org/security/2017/dsa-3791 http://www.openwall.com/lists/oss-security/2017/02/07/2 http://www.securityfocus.com/bid/96037 http://www.securitytracker.com/id/1037794 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=7892032cfe67f4bde6fc2ee967e45a8fbaf33756 https://source.android.com/security/bulletin/2017-09-01 https://usn.ubuntu.com/3754-1 • CWE-125: Out-of-bounds Read •

A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory. Se ha encontrado un fallo en el manejo del kernel de Linux para borrar los atributos SELinux de los ficheros /proc/pid/attr en versiones anteriores a la 4.9.10. Una escritura vacía (null) en este archivo puede cerrar de manera inesperada el sistema haciendo que el sistema intente acceder a la memoria no mapeada del kernel.

The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag. La función tcp_splice_read en net/ipv4/tcp.c en el kernel de Linux en versiones anteriores a 4.9.11 permite a atacantes remotos provocar una denegación de servicio (bucle infinito y bloqueo débil) a través de vectores que involucran un paquete TCP con la bandera URG. A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality could allow a remote attacker to force the kernel to enter a condition in which it could loop indefinitely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ccf7abb93af09ad0868ae9033d1ca8108bdaec82 http://www.debian.org/security/2017/dsa-3804 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.11 http://www.securityfocus.com/bid/96421 http://www.securitytracker.com/id/1037897 https://access.redhat.com/errata/RHSA-2017:1372 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://access.redhat.com/errata& • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain privileges via a crafted application that makes concurrent perf_event_open system calls for moving a software group into a hardware context. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-6786.

https://notcve.org/view.php?id=CVE-2017-5986
Race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel before 4.9.11 allows local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peels off an association in a certain buffer-full state. Condición de carrera en la función sctp_wait_for_sndbuf en net/sctp/socket.c en el kernel de Linux en versiones anteriores a 4.9.11 permite a usuarios locales provocar una denegación de servicio (fallo de aserción y pánico) a través de una aplicación multihilo que despega una asociación en un cierto estado de búfer completo. It was reported that with Linux kernel, earlier than version v4.10-rc8, an application may trigger a BUG_ON in sctp_wait_for_sndbuf if the socket tx buffer is full, a thread is waiting on it to queue more data, and meanwhile another thread peels off the association being used by the first thread. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2dcab598484185dea7ec22219c76dcdd59e3cb90 http://www.debian.org/security/2017/dsa-3804 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.11 http://www.openwall.com/lists/oss-security/2017/02/14/6 http://www.securityfocus.com/bid/96222 https://access.redhat.com/errata/RHSA-2017:1308 https://bugzilla.redhat.com/show_bug.cgi?id=1420276 https://github.com/torvalds/linux/commit/2dcab598484185dea7ec22219c76 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-617: Reachable Assertion •
