Name of the Vulnerable Software and Affected Versions: versions prior to 12.0 Hotfix 91155 Description: Improper restriction of operations in the IOMMU could allow a malicious hypervisor to access guest private memory, resulting in a loss of integrity. Recommendations: At the moment, there is no...

Linux Distros Unpatched Vulnerability : CVE-2018-1059

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical...

SUSE CVE-2018-1059

The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical Addresses to Host Virtual Addresses translations. This may lead to a malicious guest exposing vhost-user backend process memory. All versions...

USN-5684-1 linux-azure vulnerabilities

It was discovered that the SUNRPC RDMA protocol implementation in the Linux kernel did not properly calculate the header size of a RPC message payload. A local attacker could use this to expose sensitive information kernel memory. CVE-2022-0812 Moshe Kol, Amit Klein and Yossi Gilad discovered tha...

USN-5655-1 linux-intel-iotg vulnerabilities

It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2021-33655 Duoming...

USN-5633-1 linux-gcp, linux-gke, linux-raspi vulnerabilities

It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2021-33655 Duoming...

A flaw was found in the VirGL virtual OpenGL renderer (virglrenderer). The virgl did not properly initialize memory when allocating a host-backed memory resource. A malicious guest could use this flaw to mmap from the guest kernel and read this uninitialized memory from the host possibly leading to information disclosure.

USN-5579-1 linux, linux-kvm, linux-lts-xenial vulnerabilities

Roger Pau Monné discovered that the Xen virtual block driver in the Linux kernel did not properly initialize memory pages to be used for shared communication with the backend. A local attacker could use this to expose sensitive information guest kernel memory. CVE-2022-26365 Roger Pau Monné...

USN-3679-1 qemu update

Ken Johnson and Jann Horn independently discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via sidechannel attacks. An attacker in the guest could use this to expose sensitive guest information, including kernel memory. This update...

SUSE-SU-2018:1492-1 Security update for dpdk-thunderxdpdk

This update fixes the following issues: - CVE-2018-1059: The DPDK vhost-user interface does not check to verify that all the requested guest physical range is mapped and contiguous when performing Guest Physical Addresses to Host Virtual Addresses translations. This may lead to a malicious guest...

USN-3651-1 qemu update

Ken Johnson and Jann Horn independently discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via sidechannel attacks. An attacker in the guest could use this to expose sensitive guest information, including kernel memory. This update...

USN-3561-1 libvirt update

It was discovered that microprocessors utilizing speculative execution and branch prediction may allow unauthorized memory reads via sidechannel attacks. This flaw is known as Spectre. An attacker in the guest could use this to expose sensitive guest information, including kernel memory. This...

ALPINE-CVE-2017-10911

The makeresponse function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS or other guest OS kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structure...

DEBIAN-CVE-2017-10911

The makeresponse function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS or other guest OS kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structure...

DEBIAN-CVE-2016-9103

The v9fsxattrcreate function in hw/9pfs/9p.c in QEMU aka Quick Emulator allows local guest OS administrators to obtain sensitive host heap memory information by reading xattribute values before writing to them...

DEBIAN-CVE-2015-8553

Xen allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory by not enabling memory and I/O decoding control bits. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-0777...
