Hello,
An heap-use-after-free issue was found in hw/net/eepro100.c:616 in
latest version 5.2.0.
This issue was found when I was debugging Qemu in monitor. When I attach
An eepro100 NIC, and reload the snapshot, the use-after-free triggers.
Qemu boot command is as follows:
./qemu-5.2.0-rc4/build/qemu-system-x86_64 -enable-kvm -boot c -m 2G -drive
format=qcow2,file=./ubuntu.img -display none -monitor stdio
(qemu) device_add i82559a,id=eepro
(qemu) device_del eepro
(qemu) savevm tag0
(qemu) loadvm tag0
-
Backtrace is as follows:
