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.
