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.
