CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2018-6927 – kernel: Integer overflow in futex.c:futux_requeue can lead to denial of service or unspecified impact
https://notcve.org/view.php?id=CVE-2018-6927
The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value. La función futex_requeue en kernel/futex.c en el kernel de Linux, en versiones anteriores a la 4.14.15, podría permitir que atacantes provoquen una denegación de servicio (desbordamiento de enteros) o que puedan causar otro tipo de impacto sin especificar desencadenando un valor wake o requeue negativo. The futex_requeue function in kernel/futex.c in the Linux kernel, before 4.14.15, might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impacts by triggering a negative wake or requeue value. 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=fbe0e839d1e22d88810f3ee3e2f1479be4c0aa4a http://www.securityfocus.com/bid/103023 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://github.com/torvalds/linux/commit/fbe0e839d1e22d88810f3ee3e2f1479be4c0aa4a https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://usn.ubuntu.com/3619-1 https://usn.ubuntu. • CWE-190: Integer Overflow or Wraparound •

CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 0CVE-2017-1000410 – kernel: Stack information leak in the EFS element
https://notcve.org/view.php?id=CVE-2017-1000410
The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. • http://seclists.org/oss-sec/2017/q4/357 http://www.securityfocus.com/bid/102101 https://access.redhat.com/errata/RHSA-2018:0654 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://access.redhat.com/errata/RHSA-2018:1170 https://access.redhat.com/errata/RHSA-2018:1319 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
