Overview

Description
A vulnerability was found in llvm llvm-project up to 22.1.6. This affects the function llvm::StringMap::insert in the library /lib/IR/ValueSymbolTable.cpp of the component ValueSymbolTable Module. The manipulation results in stack-based buffer overflow. Attacking locally is a requirement. The exploit has been made public and could be used. The presence of this vulnerability remains uncertain at this time. The LLVM project explains, that the reported behavior is outside its documented security scope and therefore not considered a security vulnerability.

  1. Heap type confusion and out-of-bounds read/write in the Apache Fory C++ implementation. When deserializing data in compatible mode, the field-skip paths do not correctly validate the declared field types against the actual data, so input with an inconsistent schema can cause type confusion and out-of-bounds memory access. Only the C++ implementation is affected; other language implementations of Apache Fory are not. This issue affects Apache Fory C++: from 0.14.0 before 1.4.0. Users are recommended to upgrade to version 1.4.0, which fixes the issue.•CVE-2026-64608
  2. A vulnerability was determined in llvm llvm-project up to 22.1.6. This impacts the function GCRelocateInst::getBasePtr in the library llvm/lib/IR/IntrinsicInst.cpp of the component Bitcode File Handler. This manipulation causes heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized. There are still doubts about whether this vulnerability truly exists. The LLVM project explains, that the reported behavior is outside its documented security scope and therefore not considered a security vulnerability.•CVE-2026-13574
