OpenSSL 3.5.4 is a security patch release. The most severe CVE fixed in this release is Moderate.

This release incorporates the following bug fixes and mitigations:

  • Fix Out-of-bounds read & write in RFC 3211 KEK Unwrap. (CVE-2025-9230)

  • Fix Timing side-channel in SM2 algorithm on 64 bit ARM. (CVE-2025-9231)

  • Fix Out-of-bounds read in HTTP client no_proxy handling. (CVE-2025-9232)

  • Reverted the synthesised OPENSSL_VERSION_NUMBER change for the release builds, as it broke some exiting applications that relied on the previous 3.x semantics, as documented in OpenSSL_version(3).
