This vulnerability represents a critical use-after-free condition in the WebGPU implementation within Google Chrome browsers prior to version 102.0.5005.115. The flaw occurs when the browser's WebGPU API processes certain JavaScript objects that have already been freed from memory, creating a scenario where malicious code can manipulate freed memory locations. This type of vulnerability falls under the common weakness enumeration CWE-416, which specifically addresses use-after-free errors in memory management. The vulnerability stems from improper handling of object lifecycles within the WebGPU API implementation, where reference counting or garbage collection mechanisms fail to properly track object validity during asynchronous operations. When a WebGPU object is destroyed but references to it persist in JavaScript code, subsequent operations on those references can trigger memory corruption as the freed memory gets reallocated for other purposes. The attack vector involves a remote adversary who crafts a malicious HTML page containing specific WebGPU API calls that exploit this race condition between object destruction and reference access. This particular vulnerability enables arbitrary code execution in the context of the browser's renderer process, potentially allowing attackers to bypass security boundaries and escalate privileges. The operational impact extends beyond simple memory corruption, as it can lead to complete browser compromise and potential system access. The exploitability is enhanced by the fact that WebGPU is increasingly enabled by default in modern browsers, making the attack surface more prevalent. According to the attack technique framework, this vulnerability aligns with ATT&CK technique T1059.007 for command and scripting interpreter, specifically through JavaScript execution, and T1068 for exploit for privilege escalation. The remediation strategy requires immediate browser updates to patch the memory management implementation in the WebGPU API. Additionally, implementing stricter memory validation checks and enhancing the object lifecycle management within the browser's JavaScript engine would provide additional defense layers. Organizations should also consider monitoring for suspicious WebGPU API usage patterns and implementing content security policies that limit exposure to potentially malicious WebGPU implementations. The vulnerability highlights the complexity of modern browser security architectures where API implementations must maintain strict memory safety guarantees while providing high-performance graphics capabilities.
