| Mauro Matteo Cascella | 2021-12-22 15:31:31 UTC | Doc Text | A NULL pointer dereference issue was found in the block mirror layer of QEMU. The `self` pointer is dereferenced in mirror_wait_on_conflicts() without ensuring that it's not NULL. A malicious unprivileged user within the guest could use this flaw to crash the QEMU process on the host when writing data reaches the threshold of mirroring node. | |
