A flaw was found in the Linux kernel's cryptographic module, specifically within the `cc_mac_digest()` function of the `ccree` component. This vulnerability is a memory leak that occurs when a specific mapping operation fails to release allocated memory. Over time, this unreleased memory could lead to a Denial of Service (DoS) due to resource exhaustion, impacting system stability and availability.
