CVE-2026-6361: Heap buffer overflow in Google Chrome
Heap buffer overflow in PDFium in Google Chrome on Windows prior to 147.0.7727.101 allowed a remote attacker who convinced a user to engage in specific UI gestures to execute arbitrary code inside a sandbox via a crafted PDF file. (Chromium security severity: High)
AI Analysis
Technical Summary
This vulnerability involves a heap buffer overflow in PDFium, the PDF rendering engine used by Google Chrome on Windows. An attacker can exploit this by delivering a specially crafted PDF file and tricking the user into performing certain UI gestures, which leads to arbitrary code execution inside the sandbox environment. The issue affects Chrome versions prior to 147.0.7727.101 and was assigned CVE-2026-6361. Google has published a stable channel update to fix this vulnerability.
Potential Impact
Successful exploitation could allow remote code execution within the sandboxed environment of Chrome, potentially leading to further compromise of the affected system depending on sandbox escape techniques. However, no active exploits have been reported in the wild so far.
Mitigation Recommendations
Google has released an update in Chrome version 147.0.7727.101 that addresses this vulnerability. Users and administrators should update to this version or later to mitigate the risk. Since this is not a cloud service, remediation requires updating the client software. Patch status is confirmed by the vendor advisory linked.
