[Qemu-devel] possible bug in block-vmdk.c

[Rosen Sharma]

bdrv_delete(s->hd) frees the memory pointed to by s->hd. 

vmdk_parent_close accesses the freed memory?

----

static void vmdk_close(BlockDriverState *bs)
{
    BDRVVmdkState *s = bs->opaque;

    qemu_free(s->l1_table);
    qemu_free(s->l2_cache);
    bdrv_delete(s->hd);
    // try to close parent image, if exist
    vmdk_parent_close(s->hd);
}
