Incus is a system container and virtual machine manager. Prior to version 7.2.0, instance snapshots ignore the `restricted.containers.lowlevel=block` setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as `raw.lxc` and `raw.qemu`. Version 7.2.0 patches the issue.

CVE-2026-48751 [CRITICAL] CWE-863 incus: Incus has a restricted project bypass leading to arbitrary command execution
incus: Incus has a restricted project bypass leading to arbitrary command execution
Incus is a system container and virtual machine manager. Prior to version 7.2.0, instance snapshots ignore the `restricted.containers.lowlevel=block` setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as `raw.lxc` and `raw.qemu`. Version 7.2.0 patches the issue.
A flaw was found in Incus, a container and virtual machine manager. Instance snapshots do not enforce container restriction settings, allowing a user to execute arbitrary commands on the server through lowlevel hooks.
Statement: Incus is not shipped in any Red Hat product. The community Fedora package is affected.
Mitigation: No mitigation is needed as Incus is not shipped in any Red Hat product.

### Summary
Instance snapshots ignore the `restricted.containers.lowlevel=block` setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as `raw.lxc` and `raw.qemu`.
### Details
Instance snapshots ignore the `restricted.containers.lowlevel=block` setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as `raw.lxc` and `raw.qemu`.
As snapshots can be moved from one server to another, a malicious instance+snapshot can be crafted locally, moved to a restricted project and the snapshot restored for arbitrary command execution.
In practice, this allows a malicious actor to execute arbitrary commands on the host with root pr
