elfloader
概要 elfloader は、ELFファイル用の超シンプルなローダーで、ELFのフラットなインメモリ表現を生成します。 これをRustと組み合わせれば、適切で安全な高水準言語でシェルコードを書くことができます。LLVMがターゲットにできる任意のターゲット（非常にエキゾチックなプラットフォームやABI向けのカスタムターゲット仕様を含む）を使用できます。32ビットシステムでの u64 の使用、境界チェック付き配列、アロケーションのドロップ処理などをお楽しみください: これは単純に、すべての LOAD セクションを連結し、ギャップがある場合はゼロ埋めを行い、1つの大きなフラットファイルにします...
UBUNTU-CVE-2025-40245
In the Linux kernel, the following vulnerability has been resolved: nios2: ensure that memblock.currentlimit is set when setting pfn limits On nios2, with CONFIGFLATMEM set, the kernel relies on memblockgetcurrentlimit to determine the limits of memmap, in particular for maxlowpfn. Unfortunately,...
CVE-2025-40245
CVE-2025-40245 affects the Linux kernel on the Nios II platform with CONFIG_FLATMEM. The issue is that memblock.current_limit may not be properly initialized during pfn limit setup, allowing max_low_pfn to exceed max_pfn and risk kernel paging failures or a kernel panic. The fix pre-calculates me...
