CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 1CVE-2019-3844 – systemd - DynamicUser can Create setuid Binaries when Assisted by Another Process
https://notcve.org/view.php?id=CVE-2019-3844
It was discovered that a systemd service that uses DynamicUser property can get new privileges through the execution of SUID binaries, which would allow to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled. Se ha descubierto una vulnerabilidad en el servicio systemd que utilice la propiedad DynamicUser pudiendo obtener nuevos privilegios a través de la ejecución de binarios SUID, los cuales podrían permitir crear binarios pertenecientes al servicio transient group con el bit setgid, Un atacante local podría utilizar este fallo para acceder a recursos que pertenezcan a otro servicio futuro cuando el GID fuese reciclado.

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 •

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.
