CVSS: 7.0EPSS: 0%CPEs: 8EXPL: 0CVE-2016-10088 – kernel: Use after free in SCSI generic device interface (CVE-2016-9576 regression)
https://notcve.org/view.php?id=CVE-2016-10088
The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. La implementación sg en el kernel Linux hasta la versión 4.9 no restringe correctamente operaciones de escritura en situaciones donde la opción KERNEL_DS está activa, lo que permite a usuarios locales leer o escribir a ubicacioes arbitrarias de memoria de kernel o provocar una denegación de servicio (uso despues de liberación) aprovechando el acceso al dispositivo /dev/sg, relacionado con block/bsg.c y drivers/scsi/sg.c. NOTA: esta vulnerabilidad existe debido a una reparación incompleta de CVE-2016-9576. It was found that the fix for CVE-2016-9576 was incomplete: the Linux kernel's sg implementation did not properly restrict write operations in situations where the KERNEL_DS option is set. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=128394eff343fc6d2f32172f03e24829539c5835 http://rhn.redhat.com/errata/RHSA-2017-0817.html http://www.openwall.com/lists/oss-security/2016/12/30/1 http://www.securityfocus.com/bid/95169 http://www.securitytracker.com/id/1037538 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://github.com/torvalds/linux • CWE-416: Use After Free •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2016-9685 – kernel: Memory leaks in xfs_attr_list.c error paths
https://notcve.org/view.php?id=CVE-2016-9685
Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel before 4.5.1 allow local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations. Múltiples fugas de memoria en rutas de error en fs/xfs/xfs_attr_list.c en el kernel de Linux en versiones anteriores a 4.5.1 permiten a usuarios locales provocar una denegación de servicio (consumo de memoria) a través de operaciones de archivo de sistema XFS manipuladas. A flaw was found in the Linux kernel's implementation of XFS file attributes. Two memory leaks were detected in xfs_attr_shortform_list and xfs_attr3_leaf_list_int when running a docker container backed by xfs/overlay2. A dedicated attacker could possible exhaust all memory and create a denial of service situation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2e83b79b2d6c78bf1b4aa227938a214dcbddc83f http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.1 http://www.openwall.com/lists/oss-security/2016/11/30/1 http://www.securityfocus.com/bid/94593 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://bugzilla.redhat.com/show_bug.cgi?id=1396941 https: • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2016-9793
The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option. La función sock_setsockopt en net/core/sock.c en el kernel de Linux en versiones anteriores a 4.8.14 no maneja adecuadamente valores negativos de sk_sndbuf y sk_rcvbuf, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente tener otros impactos no especificados aprovechando la capacidad CAP_NET_ADMIN para una llamada al sistema setsockopt manipulada con la opción (1) SO_SNDBUFFORCE o (2) SO_RCVBUFFORCE. A flaw was found in the Linux kernel's implementation of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt() system call. Users with non-namespace CAP_NET_ADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative. This could adversely affect memory allocations and create situations where the system could crash or cause memory corruption. • https://www.exploit-db.com/exploits/41995 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b98b0bc8c431e3ceb4b26b0dfc8db509518fb290 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.14 http://www.openwall.com/lists/oss-security/2016/12/03/1 http://www.securityfocus.com/bid/94655 http://www.securitytracker.com/id/1037968 https://access.redhat.com/errata/RHSA-2017:0931 https://access.redhat.com/errata/RHSA-2017:0932 https://access.redhat. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
