CVE-2019-11810 – kernel: a NULL pointer dereference in drivers/scsi/megaraid/megaraid_sas_base.c leading to DoS
https://notcve.org/view.php?id=CVE-2019-11810
An issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free. Fue descubierto un fallo en el kernel de Linux anterior a 5.0.7. Una desreferencia de puntero NULL puede ocurrir cuando falla megasas_create_frame_pool() en megasas_alloc_cmds() en drivers/scsi/megaraid/megaraid_sas_base.c. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00056.html http://www.securityfocus.com/bid/108286 https://access.redhat.com/errata/RHSA-2019:1959 https://access.redhat.com/errata/RHSA-2019:1971 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:2736 https://access.redhat.com/errata/RHSA-2019:2837 https • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •

udp_gro_receive_segment in net/ipv4/udp_offload.c in the Linux kernel 5.x before 5.0.13 allows remote attackers to cause a denial of service (slab-out-of-bounds memory corruption) or possibly have unspecified other impact via UDP packets with a 0 payload, because of mishandling of padded packets, aka the "GRO packet of death" issue. udp_gro_receive_segment en net/ipv4/udp_offload.c en el kernel de Linux versiones desde la 5.x hasta la 5.0.13 permite a los atacantes remotos causar una denegación de servicio (corrupción de memoria fuera de límites) o posiblemente tener otro impacto no especificado a través de paquetes UDP con una carga útil de 0, debido a un manejo incorrecto de los paquetes de relleno, también conocido como el problema del "GRO packet of death". • http://www.openwall.com/lists/oss-security/2019/05/02/1 http://www.openwall.com/lists/oss-security/2019/05/05/4 http://www.securityfocus.com/bid/108142 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.13 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=4dd2b82d5adfbe0b1587ccad7a8f76d826120f37 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z7CYLTCIRTKUB4R2TLLUYPZLDQL44OBG https://security.netapp.com/advisory/ • CWE-787: Out-of-bounds Write •
CVE-2018-20510
https://notcve.org/view.php?id=CVE-2018-20510
The print_binder_transaction_ilocked function in drivers/android/binder.c in the Linux kernel 4.14.90 allows local users to obtain sensitive address information by reading "*from *code *flags" lines in a debugfs file. La función print_binder_transaction_ilocked en drivers/android/binder.c en el kernel de Linux versión 4.14.90 permite a los usuarios locales obtener información sensible de direcciones, leyendo líneas "*from *code *flags" en un archivo de depuración. • http://www.securityfocus.com/bid/108125 https://github.com/Yellow-Pay/CVE/blob/master/CVE-2018-20510 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVE-2019-11599 – Linux - Missing Locking Between ELF coredump code and userfaultfd VMA Modification
https://notcve.org/view.php?id=CVE-2019-11599
The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c. La implementación del coredump en el kernel de Linux en versiones anteriores a 5.0.10, no utiliza mecanismos de bloqueo u otros mecanismos para evitar cambios en el layout de vma o en los flags vma mientras se ejecuta, lo que permite a los usuarios locales obtener información sensible, causar una denegación de servicio o posiblemente tener otro impacto no especificado al activar una condición de carrera con llamadas mmget_not_zero o get_task_mm. Esto está relacionado con fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, y drivers/infiniband/core/uverbs_main.c A flaw was found in the Linux kernel where the coredump implementation does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs. This allows local users to obtain sensitive information, cause a denial of service (DoS), or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. • https://www.exploit-db.com/exploits/46781 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/152663/Linux-Missing-Lockdown.html http://packetstormsecurity.com/files/153702/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/04/29/1 http://www.openwall.com/lists/oss-security/2019/04/29/2 http://www& • CWE-667: Improper Locking •
