Subject: Re: CVE request: Qemu net: vmxnet3: use after free while writing

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

> Quick Emulator(Qemu) built with the VMWARE VMXNET3 NIC device support is
> vulnerable to a use-after-free issue. It could occur while writing to the
> device once it's disabled.
> 
> A privileged user inside guest could use this issue to crash the Qemu
> instance resulting in DoS.

>> Vmxnet3 device emulator does not check if the device is active,
>> before using it for write. It leads to a use after free issue,
>> if the vmxnet3_io_bar0_write routine is called after the device is
>> deactivated. Add check to avoid it.
