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-2019-14835 – 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.

CVE-2019-14822 – ibus: missing authorization allows local attacker to access the input bus of another user
https://notcve.org/view.php?id=CVE-2019-14822
16 Sep 2019 — A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user.

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.

12 Sep 2019 — hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in certain situations because source address validation is mishandled. This is a denial of service that should have been prevented by PMF (aka management frame protection). The attacker must send a crafted 802.11 frame from a location that is within the 802.11 communications range. hostapd versiones anteriores a 2.10 y wpa_supplicant versiones anteriores a 2.10, permiten una indicación incorrecta de desconexión... • http://www.openwall.com/lists/oss-security/2019/09/12/6 • CWE-346: Origin Validation Error •
