A flaw was found in the Linux kernel's macb network driver. The driver improperly handles the unregistration of fixed rate clocks, causing a resource leak. This issue can lead to resource exhaustion, potentially allowing a local attacker to cause a Denial of Service (DoS) by making the system unresponsive or unstable.
