CVSS: 7.7EPSS: 0%CPEs: 29EXPL: 0CVE-2019-3900 – Kernel: vhost_net: infinite loop while receiving packets leads to DoS
https://notcve.org/view.php?id=CVE-2019-3900
An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. Se encontró un problema de bucle infinito en el módulo del núcleo vhost_net en el kernel de Linux versiones anteriores a 5.1-rc6 inclusive, mientras manejaba los paquetes entrantes en handle_rx(). Puede ocurrir cuando un extremo envía los paquetes más rápido de lo que el otro extremo los procesa. • http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.securityfocus.com/bid/108076 https://access.redhat.com/errata/RHSA-2019:1973 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3220 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://access.redhat.com/errata/RHSA-2019:3836 http • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 5.5EPSS: 0%CPEs: 24EXPL: 0CVE-2019-3882 – kernel: denial of service vector through vfio DMA mappings
https://notcve.org/view.php?id=CVE-2019-3882
A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable. Se encontró un fallo en la implementación de la interfaz vfio del kernel de Linux que permite la violación del límite de memoria bloqueada del usuario. Si un dispositivo está vinculado a un controlador vfio, como vfio-pci, y al atacante local se le otorga la propiedad del dispositivo, puede provocar un agotamiento de la memoria del sistema y, por lo tanto, una Denegación de Servicio( DoS) (DoS). • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3882 https://l • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.8EPSS: 0%CPEs: 13EXPL: 2CVE-2019-11487 – kernel: Count overflow in FUSE request leading to use-after-free issues.
https://notcve.org/view.php?id=CVE-2019-11487
The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests. El kernel de Linux, en versiones anteriores a 5.1-rc5, permite el desbordamiento de la cuenta de referencia de página->_refcount, con los consiguientes problemas de uso de memoria después de su liberación, si existen alrededor de 140 GiB de RAM. Esto está relacionado con fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, y mm/hugetlb.c. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00040.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://www.openwall.com/lists/oss-security/2019/04/29/1 http://www.securityfocus.com/bid/108054 https://access.redhat.com/errata/RHSA-2019:2703 https://access.redhat.com/errata/RHSA-2019:2741 https://access.redhat.com/errata/RHSA-2020:0174 https://bugs.chrom • CWE-416: Use After Free •
