CVE-2026-55971 [CRITICAL] CWE-122 thrift: Apache Thrift C++ bindings: Remote code execution via heap-based buffer overflow
thrift: Apache Thrift C++ bindings: Remote code execution via heap-based buffer overflow
A flaw was found in Apache Thrift C++ bindings. A remote, unauthenticated attacker can exploit a heap-based buffer overflow vulnerability without user interaction. This can lead to arbitrary code execution, allowing the attacker to gain full control over the affected system, compromise data, and cause a denial of service.
Statement: This flaw affects the C++ implementation of Apache Thrift, specifically the ZLIB-enabled THeaderTransport (THeaderTransport::untransform()), which is reachable when a Thrift client or server negotiates the Header transport protocol with ZLIB compression enabled over a network connection. Red Hat ships the affected C++ package (thrift) in RHEL AI and in the Fedora/EPEL com
No detection rules found.
No public exploits indexed.
