CVE-2022-2097
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q (Affected 1.1.1-1.1.1p).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAES OCB mode for 32-bit x86 platforms using AES-NI assembly optimization fails to encrypt the full data length under certain conditions, exposing 16 bytes of either pre-existing memory content or plaintext (in in-place encryption scenarios). OpenSSL TLS/DTLS are unaffected since OCB cipher suites are not supported.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify OpenSSL versionRun 'openssl version' or check the library file version (e.g., /usr/lib/libssl.so.1.1 or libssl.so.3)Affected if Installed version is >= 1.1.1 and < 1.1.1q, or >= 3.0.0 and < 3.0.5
-
Confirm system architectureRun 'uname -m' or check for 32-bit x86 environment (i686, i386, or 32-bit kernel on x86_64 hardware)Affected if Running on a 32-bit x86 platform (i686 or i386)
-
Verify AES-NI hardware supportCheck /proc/cpuinfo for 'aes' flag or run 'grep -o aes /proc/cpuinfo'Affected if AES-NI instructions are available and potentially being used by OpenSSL
-
Detect OCB mode cipher usageReview application configurations, certificates, or code that uses OpenSSL ciphersuites containing 'OCB' (e.g., aes-128-ocb, aes-256-ocb) or check SSL/TLS configurations for OCB cipher listingsAffected if Applications or configurations are actively using OCB mode ciphers with OpenSSL on the affected system
A user is affected if they are running a vulnerable OpenSSL version (1.1.1-1.1.1q or 3.0.0-3.0.5) on a 32-bit x86 system with AES-NI support while using OCB mode encryption for in-place operations.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.1.1q3.0.5
Upgrade OpenSSL to version 3.0.5 or 1.1.1q. Organizations using 32-bit x86 systems with AES-NI and OCB mode should prioritize patching and verify cryptographic operations.
OpenSSL 1.1.1q (for 1.1.1 branch) or OpenSSL 3.0.5 (for 3.0 branch)
- Identify the OpenSSL version currently installed on the system using 'openssl version' or checking the package manager
- For systems using OpenSSL 1.1.1x: upgrade to OpenSSL 1.1.1q or later
- For systems using OpenSSL 3.0.x: upgrade to OpenSSL 3.0.5 or later
- Verify the upgrade was successful by checking the new version with 'openssl version'
- For embedded systems (H300s/H500s/H700s firmware, NetApp connectors, Active IQ Unified Manager): contact the vendor for firmware/software updates that include the OpenSSL patch
- For Linux distributions (Fedora, Debian): apply distribution-specific security updates that include the fixed OpenSSL packages
