CVSS: 6.2EPSS: 0%CPEs: 1EXPL: 0CVE-2017-7495 – kernel: ext4: power failure during write(2) causes on-disk information leak
https://notcve.org/view.php?id=CVE-2017-7495
fs/ext4/inode.c in the Linux kernel before 4.6.2, when ext4 data=ordered mode is used, mishandles a needs-flushing-before-commit list, which allows local users to obtain sensitive information from other users' files in opportunistic circumstances by waiting for a hardware reset, creating a new file, making write system calls, and reading this file. En el archivo fs/ext4/inode.c en el kernel de Linux anterior a versión 4.6.2, cuando es usado el modo data=ordered de ext4, maneja inapropiadamente una lista de necesidades de descarga antes de confirmar, lo que permite a los usuarios locales obtener información confidencial de los archivos de otros usuarios en circunstancias oportunistas al esperar un reinicio del hardware, crear un archivo nuevo, hacer llamadas al sistema de escritura y leer este archivo. A vulnerability was found in the Linux kernel where filesystems mounted with data=ordered mode may allow an attacker to read stale data from recently allocated blocks in new files after a system 'reset' by abusing ext4 mechanics of delayed allocation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=06bd3c36a733ac27962fea7d6f47168841376824 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.6.2 http://www.openwall.com/lists/oss-security/2017/05/15/2 http://www.securityfocus.com/bid/98491 https://bugzilla.redhat.com/show_bug.cgi?id=1450261 https://github.com/torvalds/linux/commit/06bd3c36a733ac27962fea7d6f47168841376824 https://source.android.com/security/bulletin/2017-09-01 https://access.redhat.com/security • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-665: Improper Initialization •

The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel through 4.11.1 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface. La función ipxitf_ioctl en el archivo net/ipx/af_ipx.c en el kernel de Linux hasta la versión 4.11.1, maneja inapropiadamente conteos de referencias, lo que permite a los usuarios locales causar una denegación de servicio (uso de memoria previamente liberada) o posiblemente tener otro impacto no especificado por medio de una llamada ioctl SIOCGIFADDR fallida para una interfaz de IPX. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ee0d8d8482345ff97a75a7d747efc309f13b0d80 http://www.debian.org/security/2017/dsa-3886 http://www.securityfocus.com/bid/98439 http://www.securitytracker.com/id/1039237 https://bugzilla.redhat.com/show_bug.cgi?id=1447734 https://github.com/torvalds/linux/commit/ee0d8d8482345ff97a75a7d747efc309f13b0d80 https://patchwork.ozlabs.org/patch/757549 https://source.android.com/security/bulletin/2017-09-01 • CWE-416: Use After Free •

The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow. La función edge_bulk_in_callback en drivers/usb/serial/io_ti.c en el kernel de Linux anterior a 4.10.4 permite a los usuarios locales obtener información sensible (en el dmesg ringbuffer y syslog) de la memoria del kernel no inicializada usando un dispositivo USB manipulado (aparentando ser un io_ti USB serie) para activar un desbordamiento inferior de enteros. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=654b404f2a222f918af9b0cd18ad469d0c941a8e http://www.debian.org/security/2017/dsa-3886 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.10.4 http://www.securityfocus.com/bid/98451 https://github.com/torvalds/linux/commit/654b404f2a222f918af9b0cd18ad469d0c941a8e • CWE-191: Integer Underflow (Wrap or Wraparound) •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 2CVE-2017-7472 – Linux Kernel < 4.10.13 - 'keyctl_set_reqkey_keyring' Local Denial of Service
https://notcve.org/view.php?id=CVE-2017-7472
The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls. El subsistema KEYS en el kernel de Linux anterior a 4.10.13 permite a los usuarios locales causar una denegación de servicio (consumo de memoria) a través de una serie de llamadas KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring. A vulnerability was found in the Linux kernel where the keyctl_set_reqkey_keyring() function leaks the thread keyring. This allows an unprivileged local user to exhaust kernel memory and thus cause a DoS. Linux Kernel versions prior to 4.10.13 suffer from a keyctl_set_reqkey_keyring local denial of service vulnerability. • https://www.exploit-db.com/exploits/42136 https://github.com/homjxi0e/CVE-2017-7472 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c9f838d104fed6f2f61d68164712e3204bf5271b http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://openwall.com/lists/oss-security/2017/05/11/1 http://www.securityfocus.com/bid/98422 http://www.securitytracker.com/id/1038471 https://access.redhat.com/errata/RHSA-2018:0151 https://access.redhat.com/errat • CWE-400: Uncontrolled Resource Consumption CWE-404: Improper Resource Shutdown or Release •
