Title
xen/privcmd: restrict usage in unprivileged domU
Summary
In the Linux kernel, the following vulnerability has been resolved: xen/privcmd: restrict usage in unprivileged domU The Xen privcmd driver allows to issue arbitrary hypercalls from user space processes. This is normally no problem, as access is usually limited to root and the hypervisor will deny any hypercalls affecting other domains. In case the guest is booted using secure boot, however, the privcmd driver would be enabling a root user process to modify e.g. kernel memory contents, thus breaking the secure boot feature. The only known case where an unprivileged domU is really needing to use the privcmd driver is the case when it is acting as the device model for another guest. In this case all hypercalls issued via the privcmd driver will target that other guest. Fortunately the privcmd driver can already be locked down to allow only hypercalls targeting a specific domain, but this mode can be activated from user land only today. The target domain can be obtained from Xenstore, so when not running in dom0 restrict the privcmd driver to that target domain from the beginning, resolving the potential problem of breaking secure boot. This is XSA-482 --- V2: - defer reading from Xenstore if Xenstore isn't ready yet (Jan Beulich) - wait in open() if target domain isn't known yet - issue message in case no target domain found (Jan Beulich)

This is normally no problem, as access is\\nusually limited to root and the hypervisor will deny any hypercalls\\naffecting other domains.\\n\\nIn case the guest is booted using secure boot, however, the privcmd\\ndriver would be enabling a root user process to modify e.g. kernel\\nmemory contents, thus breaking the secure boot feature.\\n\\nThe only known case where an unprivileged domU is really needing to\\nuse the privcmd driver is the case when it is acting as the device\\nmodel for another guest. In this case all hypercalls issued via the\\nprivcmd driver will target that other guest.\\n\\nFortunately the privcmd driver can already be locked down to allow\\nonly hypercalls targeting a specific domain, but this mode can be\\nactivated from user land only today.\\n\\nThe target domain can be obtained from Xenstore, so when not running\\nin dom0 restrict the privcmd driver to that target domain from the\\nbeginning, resolving the potential problem of breaking secure boot.\\n\\nThis is XSA-482\\n\\n---\\nV2:\\n- defer reading from Xenstore if Xenstore isn\u0027t ready yet (Jan Beulich)\\n- wait in open() if target domain isn\u0027t known yet\\n- issue message in case no target domain found (Jan Beulich)\"},{\"lang\":\"es\",\"value\":\"En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\\n\\nxen/privcmd: restringir el uso en domU no privilegiado\\n\\nEl controlador Xen privcmd permite emitir hiperllamadas arbitrarias desde procesos de espacio de usuario.
