CVE-2021-26933

CVE-2021-26933 affects the Xen hypervisor (Xen 4.9–4.14.x) on ARM: a guest can influence cache-bypass behavior, and cache-cleaning may occur before scrub verification, so there is no guarantee that all writes have reached memory before handing the page to the guest. The practical consequence is p...
