CVE-2024-8636: 
vulnerability analysis and mitigation

A high-severity heap buffer overflow vulnerability (CVE-2024-8636) was discovered in the Skia component of Google Chrome versions prior to 128.0.6613.137. The vulnerability was reported by security researcher Renan Rios (@hyhy100) on August 22, 2024, and was publicly disclosed on September 10, 2024. This security flaw affects Google Chrome installations across Windows, Mac, and Linux operating systems ([Chrome Release](https://chromereleases.googleblog.com/2024/09/stable-channel-update-for-desktop10.html)).

The vulnerability is classified as a heap buffer overflow (CWE-122) and out-of-bounds write (CWE-787) issue in the Skia graphics engine of Google Chrome. It received a CVSS v3.1 base score of 8.8 (High), with a vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating network accessibility, low attack complexity, no privileges required, and user interaction needed for exploitation (NVD).

The vulnerability could allow a remote attacker to potentially exploit heap corruption through a specially crafted HTML page, potentially leading to arbitrary code execution with the same privileges as the Chrome browser process. The high CVSS score indicates potential severe impacts on confidentiality, integrity, and availability of the affected system (NVD).

Google has released version 128.0.6613.137/.138 for Windows, Mac, and version 128.0.6613.137 for Linux to address this vulnerability. Users are advised to update their Chrome browsers to these versions or later. The fix was released as part of a security update that addressed multiple vulnerabilities (Chrome Release).

The vulnerability was deemed significant enough to warrant a $15,000 bug bounty reward to the researcher who reported it, indicating its severity and potential impact (Chrome Release).
