Reproduced this bug with qemu-kvm-rhev-2.1.2-23.el7.x86_64 steps: # qemu-img info afl6.img result: # qemu-img info afl6.img qemu-img: Could not open 'afl6.img': Could not open 'afl6.img': Cannot allocate memory So this bug is reproduced. Verified this bug with qemu-kvm-rhev-2.3.0-6.el7.x86_64 result: # qemu-img info afl6.img qemu-img: Could not open 'afl6.img': Could not read l1 table from extent 'afl6.img': Invalid argument No overflow occurs, just report it invalid, so this bug is fixed.
