CVE-2026-46019 Details
Description
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.
A memory leak vulnerability has been identified in the Linux kernel's Atmel AES cryptographic driver. The issue arises in the buffer cleanup function, which fails to properly free all allocated memory. Specifically, the initialization function allocates four pages of memory, but the cleanup function only frees the first page, leaving three pages unreleased. This vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel stable tree. Users can upgrade to the latest version to address this issue.
