CVE-2019-12819 – kernel: use-after-free in function __mdiobus_register() in drivers/net/phy/mdio_bus.c
https://notcve.org/view.php?id=CVE-2019-12819
An issue was discovered in the Linux kernel before 5.0. The function __mdiobus_register() in drivers/net/phy/mdio_bus.c calls put_device(), which will trigger a fixed_mdio_bus_init use-after-free. This will cause a denial of service. Fue encontrado un problema en el kernel de Linux anterior a versión 5.0. La función __mdiobus_register() en el archivo drivers/net/phy/mdio_bus.c llama a put_device(), que desencadenará un uso después de liberar de fix_mdio_bus_init . • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00040.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://packetstormsecurity.com/files/154245/Kernel-Live-Patch-Security-Notice-LSN-0054-1.html http://www.securityfocus.com/bid/108768 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6ff7b060535e87c2ae14dd8548512abfdda528fb https://github.com/torvalds/linux/comm • CWE-416: Use After Free •

An issue was discovered in the Linux kernel before 4.20.15. The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller does not check for this, it will trigger a NULL pointer dereference. This will cause denial of service. This affects nfc_llcp_build_gb in net/nfc/llcp_core.c. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00040.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://packetstormsecurity.com/files/154245/Kernel-Live-Patch-Security-Notice-LSN-0054-1.html http://www.securityfocus.com/bid/108776 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=58bdd544e2933a21a51eecf17c3f5f94038261b5 https://github.com/torvalds/linux/comm • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2019-12615
An issue was discovered in get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup_const of node_info->vdev_port.name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). Se descubrió un problema en get_vdev_port_node_info en arch / sparc / kernel / mdesc.c en el kernel de Linux hasta la versión 5.1.6. Hay un kstrdup_const sin marcar de node_info-> vdev_port.name, que podría permitir que un atacante provoque una denegación de servicio (desreferencia de puntero NULL y bloqueo del sistema). • http://www.securityfocus.com/bid/108549 https://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc.git/commit/?id=80caf43549e7e41a695c6d1e11066286538b336f https://security.netapp.com/advisory/ntap-20190710-0002 https://support.f5.com/csp/article/K60924046 https://support.f5.com/csp/article/K60924046?utm_source=f5support&%3Butm_medium=RSS https://www.mail-archive.com/linux-kernel%40vger.kernel.org/msg2014901.html • CWE-476: NULL Pointer Dereference •
CVE-2019-12614 – kernel: null pointer dereference in dlpar_parse_cc_property in arch/powerrc/platforms/pseries/dlpar.c causing denial of service
https://notcve.org/view.php?id=CVE-2019-12614
An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). Se descubrió un problema en dlpar_parse_cc_property en arch / powerpc / platform / pseries / dlpar.c en el kernel de Linux hasta la versión 5.1.6. Hay un kstrdup sin marcar de prop-> name, que podría permitir que un atacante provoque una denegación de servicio (desreferencia de puntero NULL y bloqueo del sistema). A flaw was found in the way Linux kernel's Dynamic Logical Partitioning (DLPAR) functionality on PowerPC systems handled low memory conditions on device discovery. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00025.html http://packetstormsecurity.com/files/154245/Kernel-Live-Patch-Security-Notice-LSN-0054-1.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.securityfocus.com/bid/108550 https://git.kernel.org/pub/ • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2019-12456
An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a "double fetch" vulnerability. NOTE: a third party reports that this is unexploitable because the doubly fetched value is not used ** EN DISPUTA ** Se detecto un problema en MPT3COMMAND case en _ctl_ioctl_main en drivers/scsi/mpt3sas/mpt3sas_ctl.c en el kernel de Linux hasta la versión 5.1.5. Permite a los usuarios locales generar una Denegación de Servicio o posiblemente tener otro impacto no especificado al cambiar el valor de ioc_number entre dos lecturas del kernel de este valor, también conocida como una vulnerabilidad de "double fetch". NOTA: un tercero informa que esto no se puede explotar porque no se utiliza el valor doblemente obtenido. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00040.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html https://bugzilla.redhat.com/show_bug.cgi?id=1717182 https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git/commit/?h=5.3/scsi-queue&id=86e5aca7fa2927060839f3e3b40c8bd65a7e8d1e https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MDURACJVGIB •
