CVSS: 4.7EPSS: 0%CPEs: 2EXPL: 0CVE-2016-10741 – kernel: race condition between direct and memory-mapped I/O in fs/xfs/xfs_aops.c
https://notcve.org/view.php?id=CVE-2016-10741
In the Linux kernel before 4.9.3, fs/xfs/xfs_aops.c allows local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure. En el kernel de Linux, en versiones anteriores a la 4.9.3, "fs/xfs/xfs_aops.c" permite a los usuarios locales provocar una denegación de servicio (cierre inesperado del sistema) debido a que hay una condición de carrera entre el I/O directo y el mapeado con la memoria (asociado con un agujero) que se maneja con BUG_ON en vez de un fallo I/O. It was found that the Linux kernel can hit a BUG_ON() statement in the __xfs_get_blocks() in the fs/xfs/xfs_aops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUG_ON() instead of an I/O failure. This allows a local unprivileged attacker to cause a system crash and a denial of service. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=04197b341f23b908193308b8d63d17ff23232598 http://www.securityfocus.com/bid/106822 https://bugzilla.suse.com/show_bug.cgi?id=1124010 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.3 https://github.com/torvalds/linux/commit/04197b341f23b908193308b8d63d17ff23232598 https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https://access. • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-369: Divide By Zero •
CVSS: 4.6EPSS: 0%CPEs: 4EXPL: 0CVE-2018-19985 – kernel: oob memory read in hso_probe in drivers/net/usb/hso.c
https://notcve.org/view.php?id=CVE-2018-19985
The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allows arbitrary read in the kernel address space. La función hso_get_config_data en drivers/net/usb/hso.c en el kernel de Linux, hasta la versión 4.19.8, lee if_num desde el dispositivo USB (como un u8) y lo emplea para indexar un array pequeño, lo que resulta en una lectura de objetos fuera de límites (OOB) que podría permitir la lectura arbitraria en el espacio de direcciones del kernel. A flaw was found in the Linux kernel in the function hso_probe() which reads if_num value from the USB device (as an u8) and uses it without a length check to index an array, resulting in an OOB memory read in hso_probe() or hso_get_config_data(). An attacker with a forged USB device and physical access to a system (needed to connect such a device) can cause a system crash and a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2019-01/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00007.html http://packetstormsecurity.com/files/151420/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://hexhive.epfl.ch/projects/perifuzz https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-an • CWE-125: Out-of-bounds Read •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2017-18360 – kernel: Division by zero in change_port_settings in drivers/usb/serial/io_ti.c resulting in a denial of service
https://notcve.org/view.php?id=CVE-2017-18360
In change_port_settings in drivers/usb/serial/io_ti.c in the Linux kernel before 4.11.3, local users could cause a denial of service by division-by-zero in the serial device layer by trying to set very high baud rates. En change_port_settings en drivers/usb/serial/io_ti.c en el kernel de Linux, en versiones anteriores a la 4.11.3, los usuarios locales podrían provocar una denegación de servicio (DoS) por medio de una división entre cero en la capa del dispositivo en serie intentando establecer tasas de baudio muy altas. A division-by-zero in set_termios(), when debugging is enabled, was found in the Linux kernel. When the [io_ti] driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the change_port_settings() in the drivers/usb/serial/io_ti.c so that the divisor value becomes zero and causes a system crash resulting in a denial of service. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6aeb75e6adfaed16e58780309613a578fe1ee90b http://www.securityfocus.com/bid/106802 https://bugzilla.suse.com/show_bug.cgi?id=1123706 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.11.3 https://github.com/torvalds/linux/commit/6aeb75e6adfaed16e58780309613a578fe1ee90b https://usn.ubuntu.com/3933-1 https://usn.ubuntu.com/3933-2 https://access.redhat.com/security/cve/CVE-2017-18360 https://bugzilla.redhat.co • CWE-369: Divide By Zero •

A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.
