UBUNTU-CVE-2026-44967

OpenTelemetry-cpp is the C++ implementation of OpenTelemetry. Prior to release 1.27.0, the OTLP HTTP exporters traces/metrics/logs read the full HTTP response into an in-memory vector of bytes without a size cap. This is exploitable for memory exhaustion when the configured collector endpoint is...

CVE-2026-50011 Netty has unbounded pre-allocation in RedisArrayAggregator from RESP array length

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, RedisArrayAggregator pre-allocates ArrayList with initial capacity equal to the RESP array element count declared in an array header. That count is taken fro...

CVE-2026-50011

Netty CVE-2026-50011 affects RedisArrayAggregator in Netty (prior to 4.1.135.Final and 4.2.15.Final). A RESP header can claim a large initial ArrayList capacity, taken from the wire before child messages exist, enabling unbounded pre-allocation. This can cause memory consumption issues. The issue...

CVE-2026-44967

OpenTelemetry-cpp OTLP HTTP exporters (traces/metrics/logs) read entire HTTP responses into an unbounded in-memory byte vector before 1.27.0, enabling memory exhaustion if the collector endpoint is attacker-controlled or the connection is MITM. The issue is fixed in opentelemetry-cpp release 1.27...

CVE-2026-50010

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, SimpleTrustManagerFactory.engineGetTrustManagers and related paths wrap any user-supplied plain X509TrustManager in X509TrustManagerWrapper, which extends...

CVE-2026-50009 Netty QUIC stateless reset token material exposed through header-visible connection IDs

Netty is a network application framework for development of protocol servers and clients. Prior to version 4.2.15.Final, Netty QUIC exposes the stateless reset token on the network path when using the default HMAC-based connection-ID and stateless-reset-token generators. The reset token for the...
