CVE-2021-24044 describes a critical type confusion vulnerability in Facebook Hermes versions prior to v0.10.0. Attackers could trigger a segmentation fault, and potentially achieve remote code execution (RCE), by injecting invalid JavaScript code that misused 'await' and 'yield' keywords in non-async/non-generator functions. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
