CVE-2026-48040 (opens in a new tab)How to fix?
Upgrade io.netty.incubator:netty-incubator-codec-ohttp-hpke-classes-boringssl to version 0.0.22.Final or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the fallback process for deriving native memory addresses when hasMemoryAddress() returns false and sun.misc.Unsafe is unavailable. An attacker can corrupt memory of concurrent connections and disclose contents of adjacent pooled direct buffers by sending crafted OHTTP requests.
Note:
This is only exploitable if the JVM is configured to disable Unsafe access (e.g., with -Dio.netty.noUnsafe=true), a SecurityManager restricts Unsafe access, or when running on non-HotSpot JVMs.
