In the Linux kernel, the following vulnerability has been resolved:
KVM: x86/xen: Initialize Xen timer only once
Add a check for existing xen timers before initializing a new one.
Currently kvmxeninittimer() is called on every KVMXENVCPUATTRTYPETIMER, which is causing the following ODEBUG crash when vcpu->arch.xen.timer is already set.
ODEBUG: init active (active state 0) object type: hrtimer hint: xentimercallbac0 RIP: 0010:debugprintobject+0x16e/0x250 lib/debugobjects.c:502 Call Trace: _debugobjectinit debughrtimerinit debuginit hrtimerinit kvmxeninittimer kvmxenvcpusetattr kvmarchvcpuioctl kvmvcpuioctl vfsioctl
