CVSS: 4.9EPSS: 0%CPEs: 1EXPL: 0CVE-2015-6526 – kernel: perf on ppc64 can loop forever getting userlevel stacktraces
https://notcve.org/view.php?id=CVE-2015-6526
The perf_callchain_user_64 function in arch/powerpc/perf/callchain.c in the Linux kernel before 4.0.2 on ppc64 platforms allows local users to cause a denial of service (infinite loop) via a deep 64-bit userspace backtrace. Vulnerabilidad en la función perf_callchain_user_64 en arch/powerpc/perf/callchain.c en el kernel de Linux en versiones anteriores a 4.0.2 sobre plataformas ppc64, permite a usuarios locales causar una denegación de servicio (bucle infinito) a través de una traza inversa profunda en el espacio de usuario de 64-bit. A flaw was found in the way the Linux kernel's perf subsystem retrieved userlevel stack traces on PowerPC systems. A local, unprivileged user could use this flaw to cause a denial of service on the system by creating a special stack layout that would force the perf_callchain_user_64() function into an infinite loop. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9a5cbce421a283e6aea3c4007f141735bf9da8c3 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.0.2 http://www.openwall.com/lists/oss-security/2015/08/18/4 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/76401 http://www.securitytracker.com/id/1033728 http://www.ubuntu.com/usn/USN-2759-1 http://www.ubuntu.com/usn/USN-2760-1 https:& • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request. Desbordamiento de entero en la función sg_start_req en drivers/scsi/sg.c en el kernel de Linux 2.6.x hasta la versión 4.x en versiones anteriores a 4.1 permite a usuarios locales provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de un valor iov_count grande en una petición de escritura. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=451a2886b6bf90e2fb378f7c46c655450fb96e81 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fdc81f45e9f57858da6351836507fbcf1b7583ee 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://lists.opensuse.org/opensuse-security-announce/2015-11/msg00026 • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2015-3212
Race condition in net/sctp/socket.c in the Linux kernel before 4.1.2 allows local users to cause a denial of service (list corruption and panic) via a rapid series of system calls related to sockets, as demonstrated by setsockopt calls. Vulnerabilidad de condición de carrera en net/stcp/socket.c en el kernel de Linux en versiones anteriores a 4.1.2, permite a usuarios locales causar una denegación de servicio (lista corrupta y pánico) a través de una serie de llamadas al sistema relacionadas con sockets, según lo demostrado por las llamadas setsockopt. A race condition flaw was found in the way the Linux kernel's SCTP implementation handled Address Configuration lists when performing Address Configuration Change (ASCONF). A local attacker could use this flaw to crash the system via a race condition triggered by setting certain ASCONF options on a socket. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2d45a02d0166caf2627fe91897c6ffc3b19514c4 http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http://rhn.redhat.com/errata/RHSA-2015-1778.html http://rhn.redhat.com/errata/RHSA-2015-1787.html http://www.debian.org/security/2015/dsa-3329 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.1.2 http://www.ora • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking •
