Copyright © 2012 Red Hat, Inc. All rights reserved. Low 2026-06-29T14:00:09 llvm: llvm: Denial of Service via stack-based buffer overflow in StringMap::insert 3.3 CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L CWE-120

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.

A flaw was found in llvm. A local attacker could exploit a stack-based buffer overflow vulnerability in the `llvm::StringMap::insert` function. This manipulation could lead to a denial of service, making the affected system or application unavailable.

This flaw has a Low impact as it requires a local attacker to exploit a stack-based buffer overflow in the `llvm::StringMap::insert` function. Successful exploitation could lead to a denial of service, affecting the availability of systems utilizing the vulnerable LLVM component. The vulnerability is limited to local access, reducing its overall risk in typical Red Hat deployments. Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
