See https://www.mail-archive.com/qemu-devel@nongnu.org/msg1043142.html While looking into it, also found a potential memory leak. I'm sorry that I didn't find how to test this fix, because it looks a GFX card is needed. Any idea on how to test or help test are quite appreciated. Thanks Zhenzhong v2: - set dpy->edid_info to NULL in vfio_display_edid_init() err path (Marc-André) - remove a wrongly added g_free(*info) in vfio_get_dev_region_info() (Marc-André) - add R-B on patch2 Zhenzhong Duan (2): vfio/display: Fix potential memleak of edid info vfio/display: Fix vfio_display_edid_init() error path hw/vfio/display.c | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-)
