CVE-2020-11739

An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service or possibly gain privileges because of missing memory barriers in read-write unlock paths. The read-write unlock paths don't contain a memory barrier. On Arm, this means a processor is allowed to...

CVE-2020-11739

CVE-2020-11739 affects the Xen hypervisor up to 4.13.x. The issue arises from missing memory barriers in the read-write unlock paths, enabling memory reordering on ARM that can break critical-section safety. A malicious guest could cause a race in hypercall paths (e.g., grant-table operations), p...

Missing memory barriers in read-write unlock paths

ISSUE DESCRIPTION The read-write unlock paths don't contain a memory barrier. On Arm, this means a processor is allowed to re-order the memory access with the preceding ones. In other words, the unlock may be seen by another processor before all the memory accesses within the "critical" section. ...
