Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace. \nCVSS Base score: 5.9 \nCVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/167414](<https://exchange.xforce.ibmcloud.com/vulnerabilities/167414>) for the current score. \nCVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) \n \n** CVEID: **[CVE-2019-10638](<https://vulners.com/cve/CVE-2019-10638>) \n** DESCRIPTION: **In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. \nCVSS Base score: 6.5 \nCVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/163731](<https://exchange.xforce.ibmcloud.com/vulnerabilities/163731>) for the current score. \nCVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) \n \n** CVEID: **[CVE-2019-10207](<https://vulners.com/cve/CVE-2019-10207>) \n** DESCRIPTION: **A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before 4.18.0 and kernel 5.x.x.

Enterprise Linux 7.\n\nRed Hat Product Security has rated this update as having a security impact of Important.

privilege escalation, denial of service or information leaks.\n\nCVE-2019-14821\n\nMatt 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 (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-14835\n\nPeter 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 (memory corruption or crash) or possibly for privilege escalation on the host.\n\nCVE-2019-15117\n\nHui 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 (crash).\n\nCVE-2019-15118\n\nHui Peng and Mathias Payer reported unbounded recursion in the usb-audio driver's descriptor parsing code, leading to a stack overflow.

remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:\n\n - An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)\n\n - 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.

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-2019-14835)\n\n - 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. (CVE-2019-14821)\n\n - In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by default. (CVE-2019-14283)\n\n - An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in\n __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation. (CVE-2019-15666)\n\n - An issue was discovered in the Linux kernel before 4.18.7. In create_qp_common in drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of stack memory to userspace. (CVE-2018-20855)\n\n - A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before 4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.\n (CVE-2019-10207)\n\n - An issue was discovered in the Linux kernel before 5.1.17.

Two consecutive ioctls can trigger the bug: the first one should set the drive geometry with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should be called. It can be triggered by an unprivileged local user even when a floppy disk has not been inserted. NOTE: QEMU creates the floppy device by default.
