En bref
- CVE-2026-54251 est une vulnérabilité ÉLEVÉE (CVSS 8.7) touchant io.netty.incubator:netty-incubator-codec-ohttp.
- Probabilité d'exploitation dans les 30 prochains jours (EPSS) : 0.51%, plus élevée que 43.2% des vulnérabilités.
- Correctif : mettre à jour vers 0.0.23.Final ou plus récent.
Description
The netty-incubator-codec-ohttp library implements Oblivious HTTP (OHTTP) gateway and client functionality using Netty's ByteBuf memory management. When an OHTTP gateway processes encrypted client requests, it allocates a pooled direct (native off-heap) ByteBuf to hold the decrypted plaintext before the AEAD tag is verified. If the AEAD tag check fails — meaning the ciphertext is invalid — the decryption method throws a CryptoException, but the allocated buffer is never released because no try/finally block guards the allocation.
NVD description
netty-incubator-codec-ohttp implements Oblivious HTTP (OHTTP) gateway and client functionality using Netty. Prior to 0.0.23.Final, the OHTTP gateway decryption path in codec-ohttp/src/main/java/io/netty/incubator/codec/ohttp/OHttpRequestResponseContext.java allocates a pooled direct ByteBuf for decrypted plaintext before the AEAD tag is verified. When an invalid tag causes decryptChunk() to throw CryptoException, OHttpRequestResponseContext.decodeChunk() does not release the ByteBuf because the allocation is not guarded by try/finally. Repeated invalid encrypted requests can therefore leak native off-heap memory until the gateway is unable to continue serving requests. This issue is fixed in version 0.0.23.Final.
