In the Linux kernel before 5.0.3, a memory leak exits in hsr_dev_finalize() in net/hsr/hsr_device.c if hsr_add_port fails to add a port, which may cause denial of service, aka CID-6caabe7f197d. En el kernel de Linux versiones anterior a 5.0.3, se presenta una pérdida de memoria en la función hsr_dev_finalize() en el archivo net/hsr/hsr_device.c si hsr_add_port no puede agregar un puerto, lo que puede causar una denegación de servicio, también se conoce como CID-6caabe7f197d. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00035.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.3 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6caabe7f197d3466d238f70915d65301f1716626 https://github.com/torvalds/linux/commit/6caabe7f197d3466d238f70915d65301f1716626 https://security.netapp.com/advisory/ntap-20191031-0005 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 7.8EPSS: 0%CPEs: 68EXPL: 3CVE-2019-14814 – kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS
https://notcve.org/view.php?id=CVE-2019-14814
There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento de búfer en la región heap de la memoria en el kernel de Linux, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A flaw was found in the Linux kernel’s implementation of the Marvell wifi driver, which can allow a local user who has CAP_NET_ADMIN or administrative privileges to possibly cause a Denial Of Service (DOS) by corrupting memory and possible code execution. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0328&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento del búfer en la región heap de la memoria en el kernel, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0204&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 60EXPL: 0CVE-2019-14821 – Kernel: KVM: OOB memory access via mmio ring buffer
https://notcve.org/view.php?id=CVE-2019-14821
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system. Se encontró un problema de acceso fuera de límites en el kernel de Linux, todas las versiones hasta 5.3, en la manera en que el hipervisor KVM del kernel de Linux implementa la operación de escritura MMIO Coalesced. Opera en un objeto MMIO ring buffer "struct kvm_coalesced_mmio", en donde los índices de escritura "ring-)first" y "ring-)last" podrían ser suministrados por un proceso de espacio de usuario del host. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00037.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/09/20/1 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517&# • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-14835
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host.
