CVE-2019-14821 – Kernel: KVM: OOB memory access via mmio ring buffer
https://notcve.org/view.php?id=CVE-2019-14821
19 Sep 2019 — 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 potenti... • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html • CWE-787: Out-of-bounds Write •
CVE-2019-16413
https://notcve.org/view.php?id=CVE-2019-16413
18 Sep 2019 — An issue was discovered in the Linux kernel before 5.0.4. The 9p filesystem did not protect i_size_write() properly, which causes an i_size_read() infinite loop and denial of service on SMP systems. Se detectó un problema en el kernel de Linux versiones anteriores a 5.0.4. El sistema de archivos 9p no protegió apropiadamente la función i_size_write(), lo que causa un bucle infinito de la función i_size_read() y la denegación de servicio sobre los sistemas SMP. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.4 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2019-14835 – kernel: vhost-net: guest to host kernel escape during migration
https://notcve.org/view.php?id=CVE-2019-14835
17 Sep 2019 — 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 d... • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2019-15031 – kernel: powerpc: local user can read vector registers of other users' processes via an interrupt
https://notcve.org/view.php?id=CVE-2019-15031
13 Sep 2019 — In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c. En el kernel de Linux versiones hast... • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-662: Improper Synchronization •
