JVN iPedia http://jvndb.jvn.jp Advisory JVNDB-2026-017399 Linuxカーネルにおいて、以下の脆弱性が修正されました。smbのクライアントにおいて、cifs_set_cifscreds関数が平文の資格情報をログに記録する問題がありました。デバッグロギングが有効な場合、cifs_set_cifscreds()はキーのペイロードをログに記録し、平文のユーザー名とパスワードが露出してしまいます。この資格情報の露出を防ぐため、デバッグログの記録を削除しました。 cpe:/o:linux:linux_kernel https://jvndb.jvn.jp/ja/contents/2026/JVNDB-2026-017399.html Common Vulnerabilities and Exposures (CVE) CVE-2026-23303 https://www.cve.org/CVERecord?id=CVE-2026-23303 National Vulnerability Database (NVD) CVE-2026-23303 https://nvd.nist.gov/vuln/detail/CVE-2026-23303 JVNDB CWE-noinfo https://www.ipa.go.jp/security/vuln/scap/cwe.html 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/2f37dc436d4e61ff7ae0b0353cf91b8c10396e4d) https://git.kernel.org/stable/c/2f37dc436d4e61ff7ae0b0353cf91b8c10396e4d 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/54c570de9a35860dfa85fe668f23ddfda8cc7e26) https://git.kernel.org/stable/c/54c570de9a35860dfa85fe668f23ddfda8cc7e26 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/3990f352bb0adc8688d0949a9c13e3110570eb61) https://git.kernel.org/stable/c/3990f352bb0adc8688d0949a9c13e3110570eb61 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/3e182701db612ddd794ccd5ed822e6cc1db2b972) https://git.kernel.org/stable/c/3e182701db612ddd794ccd5ed822e6cc1db2b972 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/2ef0fc3bf49db2b9df36d5f44508c9e384bfa2a1) https://git.kernel.org/stable/c/2ef0fc3bf49db2b9df36d5f44508c9e384bfa2a1 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/b746a357abfb8fdb0a171d51ec5091e786d34be1) https://git.kernel.org/stable/c/b746a357abfb8fdb0a171d51ec5091e786d34be1 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/e5a3b11e07b335006371915b2da47b6056c9e3bc) https://git.kernel.org/stable/c/e5a3b11e07b335006371915b2da47b6056c9e3bc 関連文書 smb: client: Don't log plaintext credentials in cifs_set_cifscreds - kernel/git/stable/linux.git - Linux kernel stable tree (https://git.kernel.org/stable/c/ff0ece8ed04180c52167c003362284b23cf54e8d) https://git.kernel.org/stable/c/ff0ece8ed04180c52167c003362284b23cf54e8d 2026-06-03T15:37:35+09:00 2026-06-03T15:37:35+09:00
