CVE-2021-47061

A flaw was found in the Linux kernel’s Kernel-based virtual machine KVM subsystem. A bug in the code destroys devices attached to I/O buses before the bus can be nullified. This issue causes use-after-free scenarios as readers may still reference the devices on their bus version...

CVE-2021-47061 KVM: Destroy I/O bus devices on unregister failure _after_ sync'ing SRCU

In the Linux kernel, the following vulnerability has been resolved: KVM: Destroy I/O bus devices on unregister failure after sync'ing SRCU If allocating a new instance of an I/O bus fails when unregistering a device, wait to destroy the device until after all readers are guaranteed to see the new...

CVE-2021-47061

CVE-2021-47061 : Concrete details in connected advisories show a Linux kernel/KVM issue where destroying an I/O bus device must occur after unregister, and after SRCU-synchronization. The root cause is a use-after-free risk if devices are destroyed before the bus is nullified, because readers exp...
