JVN iPedia http://jvndb.jvn.jp Advisory JVNDB-2026-032051 Linuxカーネルにおいて、以下の脆弱性が修正されました。crypto: caamで、print_hex_dump_develを使用してキーの16進ダンプを保護します。*_setkey()およびgen_split_key()で機密のキー材料をダンプする際に、print_hex_dump_devel()を用いることで、CONFIG_DYNAMIC_DEBUGが有効な場合でも実行時に秘密情報が漏洩するのを防ぎます。 cpe:/o:linux:linux_kernel https://jvndb.jvn.jp/ja/contents/2026/JVNDB-2026-032051.html Common Vulnerabilities and Exposures (CVE) CVE-2026-64316 https://www.cve.org/CVERecord?id=CVE-2026-64316 National Vulnerability Database (NVD) CVE-2026-64316 https://nvd.nist.gov/vuln/detail/CVE-2026-64316 JVNDB CWE-noinfo https://www.ipa.go.jp/security/vuln/scap/cwe.html 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/6f7b8e0321f3a8fbbd267d2ac15c671ab59e919e) https://git.kernel.org/stable/c/6f7b8e0321f3a8fbbd267d2ac15c671ab59e919e 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/8b56ba10105ca34a4b75f7e33d41d96a63815591) https://git.kernel.org/stable/c/8b56ba10105ca34a4b75f7e33d41d96a63815591 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/3f57657b6ea23f933371f2c2846322f441773cee) https://git.kernel.org/stable/c/3f57657b6ea23f933371f2c2846322f441773cee 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/9a53dc0a0ae0486e164e5af3de5f99ab42c5a23e) https://git.kernel.org/stable/c/9a53dc0a0ae0486e164e5af3de5f99ab42c5a23e 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/cea7302d5d05df74cfb4107897b1ca34163c06b9) https://git.kernel.org/stable/c/cea7302d5d05df74cfb4107897b1ca34163c06b9 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/ebd37eef6e4f435e18829c0c0c9ba3a6618cb2dd) https://git.kernel.org/stable/c/ebd37eef6e4f435e18829c0c0c9ba3a6618cb2dd 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/45c0e3615e5bca5f1fc93357af8d19975c092d4f) https://git.kernel.org/stable/c/45c0e3615e5bca5f1fc93357af8d19975c092d4f 関連文書 crypto: caam - use print_hex_dump_devel to guard key hex dumps - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/8cf5fb0503129e53052fe29302379cf83891d0fb) https://git.kernel.org/stable/c/8cf5fb0503129e53052fe29302379cf83891d0fb 2026-09-04T17:50:30+09:00 2026-09-04T17:50:30+09:00
