Missing Release of Memory after Effective Lifetime

Abstraction: Variant · Status: Draft

API response cwe.mitre.org

The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.

Title
RMCP: Unauthenticated permanent session-table leak in rmcp Streamable HTTP server transport leads to remote denial-of-service
Summary
RMCP is an official Rust SDK for the Model Context Protocol. Prior to 2.0.0, the rmcp crate's stateful Streamable HTTP server in crates/rmcp/src/transport/streamable_http_server/tower.rs allows an unauthenticated client to send a well-formed JSON-RPC POST that is not an initialization request, or an initialization request with a mismatched protocol header, causing StreamableHttpService::handle_post to call LocalSessionManager.create_session before validating the message. An early validation failure returns without removing the inserted LocalSessionHandle from LocalSessionManager.sessions, permanently retaining session and channel state for the server process lifetime. Repeated requests can grow the shared session table without bound, degrade legitimate-client latency through lock contention, exhaust memory, and terminate the server. This issue is fixed in version 2.0.0.

CVE-2026-61872 (GCVE-0-2026-61872)

Title
ImageMagick before 7.1.2-26 Memory Leak via TIFF Encoder
Summary
ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the TIFF encoder when an invalid tiff:tile-geometry is specified. Supplying malformed tile geometry parameters causes allocated memory not to be released, which can lead to increased memory consumption.

Title
ImageMagick before 7.1.2-26 Memory Leak in ICON decoder
Summary
ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the ICON decoder that occurs when a memory allocation fails. Processing a crafted ICON file that triggers an allocation failure leaks memory, which may lead to a denial of service.

Mitigation MIT-41
Implementation

Strategy: Libraries or Frameworks

  • Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
  • For example, glibc in Linux provides protection against free of invalid pointers.
  • When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
  • To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Architecture and Design

Use an abstraction library to abstract away risky APIs. Not a complete solution.

Mitigation
Architecture and Design Build and Compilation

Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
