In the Linux kernel, the following vulnerability has been resolved:

crypto: atmel-aes - Fix 3-page memory leak in atmel_aes_buff_cleanup

atmel_aes_buff_init() allocates 4 pages using __get_free_pages() with ATMEL_AES_BUFFER_ORDER, but atmel_aes_buff_cleanup() frees only the first page using free_page(), leaking the remaining 3 pages. Use free_pages() with ATMEL_AES_BUFFER_ORDER to fix the memory leak.
