CVE-2019-10142
https://notcve.org/view.php?id=CVE-2019-10142
A flaw was found in the Linux kernel's freescale hypervisor manager implementation, kernel versions 5.0.x up to, excluding 5.0.17. A parameter passed to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker can use this flaw to crash the system, corrupt memory, or create other adverse security affects. Se encontró un fallo en la implementación del gestor del hipervisor freescale del kernel de Linux, versiones del kernel 5.0.x hasta 5.0.17, excluyéndola. Un parámetro pasado hacia una ioctl se comprobó incorrectamente y se utilizó en los cálculos de tamaño para el cálculo del tamaño de página. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10142 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
CVE-2019-14284
https://notcve.org/view.php?id=CVE-2019-14284
In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setup_format_params division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should be called. It can be triggered by an unprivileged local user even when a floppy disk has not been inserted. NOTE: QEMU creates the floppy device by default. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00056.html http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://packetstormsecurity.com/files/154408/Kernel-Live-Patch-Security-Notice-LSN-0055-1.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.3 https& • CWE-369: Divide By Zero •
CVE-2019-14283 – kernel: integer overflow and OOB read in drivers/block/floppy.c
https://notcve.org/view.php?id=CVE-2019-14283
In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default. En el kernel de Linux anterior a versión 5.2.3, la función set_geometry en el archivo drivers/block/floppy.c, no comprueba los campos sect y head, como es demostrado mediante un desbordamiento de enteros y lectura fuera de límites. Puede ser activado por un usuario local sin privilegios cuando se ha insertado un disquete. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00056.html http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://packetstormsecurity.com/files/154408/Kernel-Live-Patch-Security-Notice-LSN-0055-1.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.3 https& • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •

CVE-2019-13648 – kernel: denial of service in arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c via sigreturn() system call
https://notcve.org/view.php?id=CVE-2019-13648
In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled, a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn() system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c. En el kernel de Linux hasta versión 5.2.1 sobre la plataforma powerpc, cuando la memoria transaccional de hardware está deshabilitada, un usuario local puede causar una denegación de servicio (excepción de TM Bad Thing y bloqueo del sistema) por medio de una llamada de sistema de la función sigreturn() que envía una trama de señal diseñada. Esto afecta a los archivos arch/powerpc/kernel/signal_32.c y arch/powerpc/kernel/signal_64.c. A flaw was found in the PowerPc platform, where the kernel will panic if the transactional memory is disabled. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00056.html http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/07/30/1 https://git.kernel.org/torvalds/c/f16d80b75a096c52354c6e0a574993f3b0dfbdfe https://lists.debian.org/debian-lts-announce/2019/08/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
