CVE-2026-46019

A flaw was found in the Linux kernel's `atmel-aes` cryptographic driver. The `atmel_aes_buff_cleanup` function incorrectly deallocates memory, leading to a memory leak. Specifically, while `atmel_aes_buff_init()` allocates four pages of memory, `atmel_aes_buff_cleanup()` only frees one page, resulting in three pages of memory being leaked. This issue could potentially lead to a denial of service due to resource exhaustion over time.
