https://notcve.org/view.php?id=CVE-2015-8970
crypto/algif_skcipher.c in the Linux kernel before 4.4.2 does not verify that a setkey operation has been performed on an AF_ALG socket before an accept system call is processed, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that does not supply a key, related to the lrw_crypt function in crypto/lrw.c. crypto/algif_skcipher.c en el kernel Linux en versiones anteriores a 4.4.2 no verifica que una operación setkey haya sido llevada a cabo en un enchufe AF_ALG antes de que una llamada de sistema aceptada sea procesada, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULO y caída de sistema) a través de una aplicación manipulada que no aporta una llave, relacionado con la función lrw_crypt en crypto/lrw.c. The lrw_crypt() function in 'crypto/lrw.c' in the Linux kernel before 4.5 allows local users to cause a system crash and a denial of service by the NULL pointer dereference via accept(2) system call for AF_ALG socket without calling setkey() first to set a cipher key. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=dd504589577d8e8e70f51f997ad487a4cb6c026f http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.4.2 http://www.openwall.com/lists/oss-security/2016/11/04/3 http://www.securityfocus.com/bid/94217 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2437 https://access.redhat.com/errata/RHSA-2017:2444 https:// • CWE-476: NULL Pointer Dereference •
CVSS: 6.2EPSS: 0%CPEs: 1EXPL: 0CVE-2016-8645 – kernel: a BUG() statement can be hit in net/ipv4/tcp_input.c
https://notcve.org/view.php?id=CVE-2016-8645
The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. La pila TCP en el kernel Linux en versiones anteriores a 4.8.10 maneja incorrectamente el truncamiento skb, lo que permite a usuarios locales provocar una denegación de servicio (caída de sistema) a través de una aplicación manipulada que hace llamadas de sistema sendto, relacionado con net/ipv4/tcp_ipv4.c y net/ipv6/tcp_ipv6.c. It was discovered that the Linux kernel since 3.6-rc1 with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG() statement in tcp_collapse() function after making a number of certain syscalls leading to a possible system crash. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ac6e780070e30e4c35bd395acfe9191e6268bdd3 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.10 http://www.openwall.com/lists/oss-security/2016/11/11/3 http://www.openwall.com/lists/oss-security/2016/11/30/3 http://www.securityfocus.com/bid/94264 http://www.securitytracker.com/id/1037285 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https: • CWE-284: Improper Access Control CWE-617: Reachable Assertion •

https://notcve.org/view.php?id=CVE-2016-8646
The hash_accept function in crypto/algif_hash.c in the Linux kernel before 4.3.6 allows local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data. La función hash_accept en crypto/algif_hash.c en el kernel Linux en versiones anteriores a 4.3.6 permite a usuarios locales provocar una denegación de servicio (OOPS) intentando desencadenar el uso de algoritmos hash in-kernel para un enchufe que ha recibido cero bytes de datos. A vulnerability was found in the Linux kernel. An unprivileged local user could trigger oops in shash_async_export() by attempting to force the in-kernel hashing algorithms into decrypting an empty data set. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4afa5f9617927453ac04b24b584f6c718dfb4f45 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.3.6 http://www.openwall.com/lists/oss-security/2016/11/15/2 http://www.securityfocus.com/bid/94309 https://access.redhat.com/errata/RHSA-2017:1297 https://access.redhat.com/errata/RHSA-2017:1298 https://access.redhat.com/errata/RHSA-2017:1308 https://bugzilla.redhat.com/show_bug.cgi?id=1388821 https: • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2016-9084 – kernel: Integer overflow when using kzalloc in vfio driver
https://notcve.org/view.php?id=CVE-2016-9084
drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel through 4.8.11 misuses the kzalloc function, which allows local users to cause a denial of service (integer overflow) or have unspecified other impact by leveraging access to a vfio PCI device file. drivers/vfio/pci/vfio_pci_intrs.c en el kernel Linux hasta la versión 4.8.11 usa de forma incorrecta la función kzalloc, lo que permite a usuarios locales provocar una denegación de servicio (desbordamiento de entero) o tener otro posible impacto no especificado aprovechando el acceso al archivo de dispositivo vfio PCI. The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=05692d7005a364add85c6e25a6c4447ce08f913a http://rhn.redhat.com/errata/RHSA-2017-0386.html http://rhn.redhat.com/errata/RHSA-2017-0387.html http://www.openwall.com/lists/oss-security/2016/10/26/11 http://www.securityfocus.com/bid/93930 https://bugzilla.redhat.com/show_bug.cgi?id=1389259 https://github.com/torvalds/linux/commit/05692d7005a364add85c6e25a6c4447ce08f913a https://patchwork.kernel.org/patch/9373631 https:/&#x • CWE-190: Integer Overflow or Wraparound •
