A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13. A superfluous implicit page unlock for VM_SHARED hugetlbfs mapping could trigger a local denial of service (BUG). Se encontró un error en la función hugetlb_mcopy_atomic_pte en mm/hugetlb.c en el kernel de Linux en versiones anteriores a la 4.13. Un desbloqueo superfluo implícito de página para la representación hugetlbfs de VM_SHARED podría desembocar una denegación de servicio local (error). A flaw was found in the Linux kernel when freeing pages in hugetlbfs. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5af10dfd0afc559bb4b0f7e3e8227a1578333995 http://www.securityfocus.com/bid/102517 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/security/cve/CVE-2017-15127 https://bugzilla.redhat.com/show_bug.cgi?id=1525218 https://github.com/torvalds/linux/commit/5af10dfd0afc559bb4b0f7e3e8227a1578333995 • CWE-460: Improper Cleanup on Thrown Exception •

The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. La función tcpmss_mangle_packet en net/netfilter/xt_TCPMSS.c en el kernel de Linux, en versiones anteriores a la 4.11 y en versiones 4.9.x anteriores a la 4.9.36, permite que atacantes remotos provoquen una denegación de servicio (uso de memoria previamente liberada y corrupción de memoria) o, posiblemente, otro tipo de impacto sin especificar aprovechando la presencia de xt_TCPMSS en una acción iptables. The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2638fd0f92d4397884fd991d8f4925cb3f081901 http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00047.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2015-7553
Race condition in the kernel in Red Hat Enterprise Linux 7, kernel-rt and Red Hat Enterprise MRG 2, when the nfnetlink_log module is loaded, allows local users to cause a denial of service (panic) by creating netlink sockets. Una condición de carrera en el kernel en Red Hat Enterprise Linux 7, kernel-rt y Red Hat Enterprise MRG 2 permite que usuarios locales provoquen una denegación de servicio (pánico) mediante la creación de sockets netlink cuando se carga el módulo nfnetlink_log. A race-condition flaw was discovered in the kernel's netlink module creation, which can trigger a kernel panic in netlink_release->module_put for local users creating netlink sockets. The flaw is specific to Red Hat Enterprise Linux and does not affect upstream kernels. The nfnetlink_log module must be loaded before the flaw can occur. • https://bugzilla.redhat.com/show_bug.cgi?id=1288934 https://access.redhat.com/security/cve/CVE-2015-7553 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2017-7482
In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. This could possibly lead to memory corruption and possible privilege escalation. en el kernel de Linux en versiones anteriores a la 4.12, los tickets de Kerberos 5 descifrados al emplear las claves RXRPC de forma incorrecta asumen el tamaño de un campo. Esto podría conducir a un wrapping de la variable que mantiene el tamaño y en que el puntero de datos vaya más allá final del búfer. Esto podría conducir a una corrupción de memoria y a un posible escalado de privilegios. • http://seclists.org/oss-sec/2017/q2/602 http://www.securityfocus.com/bid/99299 http://www.securitytracker.com/id/1038787 https://access.redhat.com/errata/RHSA-2019:0641 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-7482 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5f2f97656ada8d811d3c1bef503ced266fcd53a0 https://www.debian.org/security/2017/dsa-3927 https://www.debian.org/security/2017/dsa-3945 https://access.redhat.com/security/cve&# • CWE-190: Integer Overflow or Wraparound •
