CVE-2026-31391

A flaw was found in the Linux kernel's atmel-sha204a component. This issue arises when the system attempts to allocate memory, and that allocation fails. If not properly handled, a resource counter, tfm_count, is not correctly decremented, leading to a resource leak. This can be exploited by a local user or process to prevent future read operations, effectively causing a Denial of Service (DoS) by making the system unresponsive to certain requests.
