CVE-2014-2915

Published: 24 April 2014

Xen 4.4.x, when running on ARM systems, does not properly restrict access to hardware features, which allows local guest users to cause a denial of service (host or guest crash) via unspecified vectors, related to (1) cache control, (2) coprocessors, (3) debug registers, and (4) other unspecified registers.

Status

Notes

Only affects ARM 32 bit, ARM 64 bit, 4.4 and newer.
Only "medium" because advisory indicates privilege escalation
is not thought possible
