CVSS: 7.5EPSS: 0%CPEs: 7EXPL: 0CVE-2016-2117 – kernel: Kernel memory leakage to ethernet frames due to buffer overflow in ethernet drivers
https://notcve.org/view.php?id=CVE-2016-2117
The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data. La función atl2_probe en drivers/net/ethernet/atheros/atlx/atl2.c en el kernel de Linux hasta la versión 4.5.2 activa incorrectamente scatter/gather I/O, lo que permite a atacantes remotos obtener información sensible de la memoria del kernel leyendo datos de paquete. It was discovered that the atl2_probe() function in the Atheros L2 Ethernet driver in the Linux kernel incorrectly enabled scatter/gather I/O. A remote attacker could use this flaw to obtain potentially sensitive information from the kernel memory. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f43bfaeddc79effbf3d0fcb53ca477cca66f3db8 http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2016/dsa-3607 http://www.openwall.com/lists/oss-security/2016/03/16/7 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.secu • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.1EPSS: 0%CPEs: 10EXPL: 0CVE-2015-8839 – kernel: ext4 filesystem page fault race condition with fallocate call.
https://notcve.org/view.php?id=CVE-2015-8839
Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local users to cause a denial of service (disk corruption) by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling. Múltiples condiciones de carrera en la implementación del sistema de archivos ext4 en el kernel de Linux en versiones anteriores a 4.5 permite a usuarios locales provocar una denegación de servicio (corrupción de disco) escribiendo a una página que está asociada con un archivo de usuario diferente después del manejo de hole punching desincronizado y de fallo de página. A flaw was found in the Linux kernel when attempting to "punch a hole" in files existing on an ext4 filesystem. When punching holes into a file races with the page fault of the same area, it is possible that freed blocks remain referenced from page cache pages mapped to process' address space. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ea3d7209ca01da209cda6f0dea8be9cc4b7a933b http://www.openwall.com/lists/oss-security/2016/04/01/4 http://www.securityfocus.com/bid/85798 http://www.securitytracker.com/id/1035455 http://www.ubuntu.com/usn/USN-3005-1 http://www.ubuntu.com/usn/USN-3006-1 http://www.ubuntu.com/usn/USN-3007-1 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https:& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 3CVE-2016-2853 – AUFS (Ubuntu 15.10) - 'allow_userns' Fuse/Xattr User Namespaces Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-2853
The aufs module for the Linux kernel 3.x and 4.x does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an aufs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program. El módulo aufs para el kernel de Linux 3.x y 4.x no restringe correctamente el espacio de nombres de montaje, lo que permite a usuarios locales obtener privilegos montando un sistema de archivos aufs sobre un sistema de archivos FUSE y luego ejecutando un programa setuid manipulado. AUFS (Ubuntu 15.10) suffers from an allow_userns fuse/xattr user namespaces privilege escalation vulnerability. • https://www.exploit-db.com/exploits/41761 http://www.halfdog.net/Security/2016/AufsPrivilegeEscalationInUserNamespaces http://www.openwall.com/lists/oss-security/2016/02/24/9 http://www.openwall.com/lists/oss-security/2021/10/18/1 http://www.securityfocus.com/bid/96839 https://sourceforge.net/p/aufs/mailman/message/34864744 • CWE-269: Improper Privilege Management •

La función ims_pcu_parse_cdc_data en drivers/input/misc/ims-pcu.c en el kernel de Linux en versiones anteriores a 4.5.1 permite a atacantes físicamente próximos provocar una denegación de servicio (caída de sistema) a través de un dispositivo USB sin interfaz para un maestro y un esclavo. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a0ad220c96692eda76b2e3fd7279f3dcd1d8a8ff http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.5.1 http://www.openwall.com/l •

https://notcve.org/view.php?id=CVE-2015-8844
The signal implementation in the Linux kernel before 4.3.5 on powerpc platforms does not check for an MSR with both the S and T bits set, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. La implementación de signal en el Kernel de Linux en versiones anteriores a 4.3.5 sobre plataformas powerpc no verifica que exista un MSR con los bits S y T establecidos, lo que permite a usuarios locales provocar una denegación de servicio (excepción TM Bad Thing exception y pánico) a través de una aplicación manipulada. A flaw was found in the Linux kernel which could cause a kernel panic when restoring machine specific registers on the PowerPC platform. Incorrect transactional memory state registers could inadvertently change the call path on return from userspace and cause the kernel to enter an unknown state and crash. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d2b9d2a5ad5ef04ff978c9923d19730cb05efd55 http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.3.5 http://www.openwall.com/lists/oss-security/2016/04/13/1 http://www.securitytracker.com/id/1035594 https://bugzilla.redhat.com/show_bug.cgi?id=1326540 https://github.com/torvalds/linux/commit/d2b9d2a5ad5ef0 • CWE-20: Improper Input Validation CWE-772: Missing Release of Resource after Effective Lifetime •
