Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2019-14821 Matt Delco reported a race condition in KVM"s coalesced MMIO facility, which could lead to out-of-bounds access in the kernel. A local attacker permitted to access /dev/kvm could use this to cause a denial of service or possibly for privilege escalation. CVE-2019-14835 Peter Pi of Tencent Blade Team discovered a missing bounds check in vhost_net, the network back-end driver for KVM hosts, leading to a buffer overflow when the host begins live migration of a VM. An attacker in control of a VM could use this to cause a denial of service or possibly for privilege escalation on the host. CVE-2019-15117 Hui Peng and Mathias Payer reported a missing bounds check in the usb-audio driver"s descriptor parsing code, leading to a buffer over-read. An attacker able to add USB devices could possibly use this to cause a denial of service . CVE-2019-15118 Hui Peng and Mathias Payer reported unbounded recursion in the usb-audio driver"s descriptor parsing code, leading to a stack overflow. An attacker able to add USB devices could use this to cause a denial of service or possibly for privilege escalation. On the amd64 architecture, and on the arm64 architecture in buster, this is mitigated by a guard page on the kernel stack, so that it is only possible to cause a crash. CVE-2019-15902 Brad Spengler reported that a backporting error reintroduced a spectre-v1 vulnerability in the ptrace subsystem in the ptrace_get_debugreg function.
