CVE-2015-1563

CVE-2015-1563 involves the ARM GIC distributor virtualization in Xen (versions 4.4.x and 4.5.x). The advisory notes that local guests can cause a denial of service by flooding the hypervisor console with log messages due to the GIC distribution path. This is the precise root cause and impact desc...

arm: vgic: incorrect rate limiting of guest triggered logging

ISSUE DESCRIPTION On ARM systems the code which deals with virtualising the GIC distributor would, under various circumstances, log messages on a guest accessible code path without appropriate rate limiting. IMPACT A malicious guest could cause repeated logging to the hypervisor console, leading ...
