Vulnerability from csaf_suse - Published: 2026-04-28 15:28 - Updated: 2026-04-28 15:28Summary
Security update for libsodium
Severity
Moderate
Notes
Title of the patch: Security update for libsodium
Description of the patch: 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 improved with 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.
