CVE-2019-7221 – Kernel: KVM: nVMX: use-after-free of the hrtimer for emulation of the preemption timer
https://notcve.org/view.php?id=CVE-2019-7221
16 Feb 2019 — The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. La implementación KVM en el kernel de Linux, hasta la versión 4.20.5, tiene un uso de memoria previamente liberada. A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested (=1) virtualization is enabled. This high resolution timer(hrtimer) runs when a L2 guest is active. After VM exit, the sync_vmcs12() timer object is stopped. • https://packetstorm.news/files/id/151713 • CWE-416: Use After Free •
CVE-2019-6974 – Linux - 'kvm_ioctl_create_device()' NULL Pointer Dereference

CVE-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
01 Feb 2019 — 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 ... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=04197b341f23b908193308b8d63d17ff23232598 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-369: Divide By Zero •
CVE-2017-18360 – kernel: Division by zero in change_port_settings in drivers/usb/serial/io_ti.c resulting in a denial of service

31 Jan 2019 — 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 baud... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6aeb75e6adfaed16e58780309613a578fe1ee90b • CWE-369: Divide By Zero •
CVE-2018-19985 – kernel: oob memory read in hso_probe in drivers/net/usb/hso.c

31 Jan 2019 — 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 lectur... • http://lists.opensuse.org/opensuse-security-announce/2019-01/msg00023.html • CWE-125: Out-of-bounds Read •
CVE-2018-16880 – Ubuntu Security Notice USN-3903-1
https://notcve.org/view.php?id=CVE-2018-16880
29 Jan 2019 — 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. Se ha encontrado un error en la función handle_rx() del controlador [vhost_net] en el kernel de Linux. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00037.html • CWE-787: Out-of-bounds Write •

CVE-2019-5489 – Kernel: page cache side channel attacks
https://notcve.org/view.php?id=CVE-2019-5489
07 Jan 2019 — The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server.

03 Jan 2019 — An issue was discovered in can_can_gw_rcv in net/can/gw.c in the Linux kernel through 4.19.13. The CAN frame modification rules allow bitwise logical operations that can be also applied to the can_dlc field. The privileged user "root" with CAP_NET_ADMIN can create a CAN frame modification rule that makes the data length code a higher value than the available CAN frame data size. In combination with a configured checksum calculation where the result is stored relatively to the end of the data (e.g. cgw_csum_... • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00035.html • CWE-787: Out-of-bounds Write •
