kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service. kernel/bpf/verifier.c en el kernel de Linux hasta la versión 4.14.8 ignora el código inalcanzable, incluso aunque sea procesado por compiladores en tiempo de ejecución o JIT. Este comportamiento, que también se considera un problema de lógica de poda de ramas incorrecta, podría ser utilizado por usuarios locales para provocar una denegación de servicio (DoS). • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c131187db2d3fa2f8bf32fdf4e9a4ef805168467 http://www.securityfocus.com/bid/102325 http://www.securitytracker.com/id/1040057 https://anonscm.debian.org/cgit/kernel/linux.git/tree/debian/patches/bugfix/all/bpf-fix-branch-pruning-logic.patch?h=stretch-security https://github.com/torvalds/linux/commit/c131187db2d3fa2f8bf32fdf4e9a4ef805168467 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/usn/ • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2017-17712 – kernel: Race condition in raw_sendmsg function allows denial-of-service or kernel addresses leak
https://notcve.org/view.php?id=CVE-2017-17712
The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel through 4.14.6 has a race condition in inet->hdrincl that leads to uninitialized stack pointer usage; this allows a local user to execute code and gain privileges. La función raw_sendmsg() en net/ipv4/raw.c en el kernel de Linux hasta la versión 4.14.6 tiene una condición de carrera en inet->hdrincl que conduce al uso de un puntero de pila no inicializado. Esto permite que un usuario local ejecute código y obtenga privilegios. A flaw was found in the Linux kernel's implementation of raw_sendmsg allowing a local attacker to panic the kernel or possibly leak kernel addresses. A local attacker, with the privilege of creating raw sockets, can abuse a possible race condition when setting the socket option to allow the kernel to automatically create ip header values and thus potentially escalate their privileges. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8f659a03a0ba9289b9aeb9b4470e6fb263d6f483 https://access.redhat.com/errata/RHSA-2018:0502 https://github.com/torvalds/linux/commit/8f659a03a0ba9289b9aeb9b4470e6fb263d6f483 https://source.android.com/security/bulletin/pixel/2018-04-01 https://usn.ubuntu.com/3581-1 https://usn.ubuntu.com/3581-2 https://usn.ubuntu.com/3581-3 https://usn.ubuntu.com/3582-1 https://usn.ubuntu.com/3582-2 https://www.debian.org/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

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 •
