The vulnerability is described as an "Out of bounds write in V8 in Google Chrome prior to 153.0.8010.36". While the Chrome Releases blog post confirms the fix and links to an internal Chromium bug ID (543557673), access to this bug report is restricted. Attempts to fetch commit information directly from the issue tracker or through general Google searches for the CVE ID did not yield specific commit hashes or code diffs. Without access to the actual patch or detailed technical analysis of the fix, it is not possible to identify the precise vulnerable functions, their file paths, or the specific changes that constitute the patch evidence. Therefore, no vulnerable functions can be confidently identified.
