  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ncrypto: atmel-aes - Fix 3-page memory leak in atmel_aes_buff_cleanup\natmel_aes_buff_init() allocates 4 pages using __get_free_pages() with\nATMEL_AES_BUFFER_ORDER, but atmel_aes_buff_cleanup() frees only the\nfirst page using free_page(), leaking the remaining 3 pages. Use\nfree_pages() with ATMEL_AES_BUFFER_ORDER to fix the memory leak.", "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." ],
