UBUNTU-CVE-2020-15852

An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port permissions of an unrelated task. This occurs because tssinvalidateiobitmap mishandling causes a loss of synchronization between the I/O bitmaps ...

Xen Input Validation Error Vulnerability (CNVD-2021-17751)

Xen is an open source virtual machine monitor product. It enables different and incompatible operating systems to run on the same computer and supports runtime migration to ensure uptime and avoid downtime. A security vulnerability exists in Xen 4.13.x and earlier versions. An attacker could...

ALPINE-CVE-2020-15566

An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a host OS crash because of incorrect error handling in event-channel port allocation. The allocation of an event-channel port may fail for multiple reasons: 1 port is already in use, 2 the memory allocation failed, or...

CVE-2020-15563

An issue was discovered in Xen through 4.13.x, allowing x86 HVM guest OS users to cause a hypervisor crash. An inverted conditional in x86 HVM guests' dirty video RAM tracking code allows such guests to make Xen de-reference a pointer guaranteed to point at unmapped space. A malicious or buggy HV...

UBUNTU-CVE-2020-15565

An issue was discovered in Xen through 4.13.x, allowing x86 Intel HVM guest OS users to cause a host OS denial of service or possibly gain privileges because of insufficient cache write-back under VT-d. When page tables are shared between IOMMU and CPU, changes to them require flushing of both...
