https://notcve.org/view.php?id=CVE-2017-17449
The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system. La función __netlink_deliver_tap_skb en net/netlink/af_netlink.c en el kernel de Linux hasta la versión 4.14.4, cuando CONFIG_NLMON está habilitado, no restringe las observaciones de mensajes Netlink a un espacio de nombres de red único, lo que permite que usuarios locales obtengan información sensible utilizando la capacidad CAP_NET_ADMIN para rastrear una interfaz nlmon para toda la actividad Netlink en el sistema.

https://notcve.org/view.php?id=CVE-2017-8824
The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state. La función dccp_disconnect en net/dccp/proto.c en el kernel de Linux hasta la versión 4.14.3 permite que usuarios locales obtengan privilegios o provoquen una denegación de servicio (uso de memoria previamente liberada) mediante una llamada del sistema de conexión AF_UNSPEC durante el estado DCCP_LISTEN. A use-after-free vulnerability was found in DCCP socket code affecting the Linux kernel since 2.6.16. This vulnerability could allow an attacker to their escalate privileges. The Linux kernel suffers from a DCCP socket use-after-free vulnerability. • https://www.exploit-db.com/exploits/43234 http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://lists.openwall.net/netdev/2017/12/04/224 http://www.openwall.com/lists/oss-security/2017/12/05/1 http://www.securityfocus.com/bid/102056 https://access.redhat.com/errata/RHSA-2018:0399 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2018:1130 https://acces • CWE-416: Use After Free •
CVSS: 7.0EPSS: 0%CPEs: 9EXPL: 3CVE-2017-1000405 – Linux Kernel - 'The Huge Dirty Cow' Overwriting The Huge Zero Page
https://notcve.org/view.php?id=CVE-2017-1000405
The Linux Kernel versions 2.6.38 through 4.14 have a problematic use of pmd_mkdirty() in the touch_pmd() function inside the THP implementation. touch_pmd() can be reached by get_user_pages(). In such case, the pmd will become dirty. This scenario breaks the new can_follow_write_pmd()'s logic - pmd can become dirty without going through a COW cycle. This bug is not as severe as the original "Dirty cow" because an ext4 file (or any other regular file) cannot be mapped using THP. Nevertheless, it does allow us to overwrite read-only huge pages. • https://www.exploit-db.com/exploits/44305 https://www.exploit-db.com/exploits/43199 http://www.securityfocus.com/bid/102032 http://www.securitytracker.com/id/1040020 https://access.redhat.com/errata/RHSA-2018:0180 https://medium.com/bindecy/huge-dirty-cow-cve-2017-1000405-110eca132de0 https://source.android.com/security/bulletin/pixel/2018-02-01 https://access.redhat.com/security/cve/CVE-2017-1000405 https://bugzilla.redhat.com/show_bug.cgi?id=1516514 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Memory leak in drivers/media/video/videobuf-core.c in the videobuf subsystem in the Linux kernel 2.6.x through 4.x allows local users to cause a denial of service (memory consumption) by leveraging /dev/video access for a series of mmap calls that require new allocations, a different vulnerability than CVE-2007-6761. NOTE: as of 2016-06-18, this affects only 11 drivers that have not been updated to use videobuf2 instead of videobuf. La pérdida de memoria en drivers/media/video/videobuf-core.c en el subsistema videobuf en el kernel de Linux 2.6.x hasta la versión 4.x permite a usuarios locales causar una denegación de servicio (consumo de memoria) aprovechando el acceso /dev/video para una serie de llamadas mmap que requieren nuevas asignaciones, una vulnerabilidad diferente a CVE-2007-6761. NOTA: a partir de 18-06-2016, esto afecta sólo a 11 controladores que no se han actualizado para utilizar videobuf2 en lugar de videobuf. • http://linuxtv.org/irc/v4l/index.php?date=2010-07-29 http://www.openwall.com/lists/oss-security/2015/02/08/4 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827340 https://bugzilla.kernel.org/show_bug.cgi?id=120571 https://bugzilla.redhat.com/show_bug.cgi?id=620629 • CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 7.8EPSS: 0%CPEs: 13EXPL: 0CVE-2018-5332 – kernel: rds_message_alloc_sgs() function doesn't validate value used during DMA page allocation causes heap out-of-bounds write
https://notcve.org/view.php?id=CVE-2018-5332
In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c). En el kernel de Linux hasta la versión 3.2, la función rds_message_alloc_sgs() no valida un valor empleado durante la asignación de página DMA, lo que conduce a una escritura fuera de límites basada en memoria dinámica (heap), relacionado con la función rds_rdma_extra_size en net/rds/rdma.c In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. 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=c095508770aebf1b9218e77026e48345d719b17c http://www.securityfocus.com/bid/102507 https://access.redhat.com/errata/RHSA-2018:0470 https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=60daca9efbb3e4109ebc1f7069543e5573fc124e https://github.com/torvalds/linux/commit/c095508770aebf1b9218e77026e48345d719b17c https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://usn.ubuntu.com/3617-1 https://usn. • CWE-787: Out-of-bounds Write •
