Subject: Re: CVE request Qemu: net: out of bounds read in net_checksum_calculate

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

> Qemu emulator built with the IP checksum routines is vulnerable to an OOB read
> access issue. It could occur while computing checksum for TCP/UDP packets, as
> the function uses payload length from the packet without checking against the
> data buffer size.
> 
> A user inside guest could use this flaw to read excessive bytes or crash the
> Qemu process resulting in DoS.
