CVE-2014-2580 [MEDIUM] CVE-2014-2580 kernel: xen: Linux netback crash trying to disable due to malformed packet
CVE-2014-2580 kernel: xen: Linux netback crash trying to disable due to malformed packet
When Linux's netback sees a malformed packet, it tries to disable the interface which serves the misbehaving frontend.
This involves taking a mutex, which might sleep. But in recent versions of Linux the guest transmit path is handled by NAPI in softirq context, where sleeping is not allowed. The end result is that the backend domain (often, Dom0) crashes with "scheduling while atomic".
Malicious guest administrators can cause denial of service. If driver domains are not in use, the impact is a host crash.
