Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the improper enforcement of resource limits in the nftables rules generation process for managed bridge networks. An attacker can exhaust the DHCP pool and disrupt network connectivity for other devices by sending numerous DHCP requests with different MAC addresses, thereby consuming all available IP leases. This also allows sending DNS requests with arbitrary MAC and IP addresses, potentially bypassing intended access controls.
