SUSE Linux Micro 6.2 libsodium Moderate Security Issues Vuln 2026-21393-1

An update that solves two vulnerabilities can now be installed.. # Security update for libsodium Announcement ID: SUSE-SU-2026:21393-1 Release Date: 2026-04-28T15:27:44Z Rating: moderate References: * bsc#1255764 * bsc#1256070 Cross-References: * CVE-2025-15444 * CVE-2025-69277 CVSS scores: * CVE-2025-15444 ( SUSE ): 6.8 CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N * CVE-2025-15444 ( NVD ): 9.8 CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H * CVE-2025-69277 ( SUSE ): 4.8 CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N * CVE-2025-69277 ( SUSE ): 4.4 CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N * CVE-2025-69277 ( NVD ): 4.5 CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N Affected Products: * SUSE Linux Micro 6.2 An update that solves two vulnerabilities can now be installed. ## Description: This update for libsodium fixes the following issues: Security fixes: * CVE-2025-15444: Cryptographic bypass via improper elliptic curve point validation (bsc#1256070). * CVE-2025-69277: incorrect validation of elliptic curve points certain custom cryptography or untrusted data to crypto_core_ed25519_is_valid_point function (bsc#1255764). Other fixes: * Update to 1.0.21 * The new crypto_ipcrypt_* functions implement mechanisms for securely encrypting and anonymizing IP addresses. * The sodium_bin2ip and sodium_ip2bin helper functions have been added to complement the crypto_ipcrypt_* functions and easily convert addresses between bytes and strings. * XOF: the crypto_xof_shake _and crypto_xof_turboshake_ functions are * standard extendable output functions. From input of any length, they can derive output of any length with the same properties as hash functions. These primitives are required by many post-quantum mechanisms, but can also be used for a wide range of applications, including key derivation, session encryption and more. * Performance of AES256-GCM and AEGIS on ARM has been improvedwith some compilers * Security: optblockers have been introduced in critical code paths to prevent compilers from introducing unwanted side channels via conditional jumps. This was observed on RISC-V targets with specific compilers and options. * Security: crypto_core_ed25519_is_valid_point() now properly rejects small- order points that are not in the main subgroup * ((nonnull)) attributes have been relaxed on some crypto_stream* functions to allow NULL output buffers when the output length is zero * A cross-compilation issue with old clang versions has been fixed * crypto_aead_aes256gcm_is_available is exported to JavaScript * Security: memory fences have been added after MAC verification in AEAD to prevent speculative access to plaintext before authentication is complete * Assembly files now include .gnu.property notes for proper IBT and Shadow Stack support when building with CET instrumentation. ## Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch". Alternatively you can run the command listed for your product: * SUSE Linux Micro 6.2 zypper in -t patch SUSE-SL-Micro-6.2-649=1 ## Package List: * SUSE Linux Micro 6.2 (aarch64 ppc64le s390x x86_64) * libsodium26-debuginfo-1.0.21-160000.1.1 * libsodium26-1.0.21-160000.1.1 * libsodium-debugsource-1.0.21-160000.1.1 ## References: * https://www.suse.com/security/cve/CVE-2025-15444.html * https://www.suse.com/security/cve/CVE-2025-69277.html * https://bugzilla.suse.com/show_bug.cgi?id=1255764 * https://bugzilla.suse.com/show_bug.cgi?id=1256070 .
