Use after free in V8 in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Use-after-free in V8, Google Chrome's JavaScript engine, prior to version 152.0.7977.65 enables remote attackers to execute arbitrary code within the Chrome sandbox by luring a user to a crafted HTML page. The CVSS 8.8 vector (AV:N/AC:L/PR:N/UI:R) confirms low-complexity, unauthenticated network delivery requiring only a single user visit, with high confidentiality, integrity, and availability impact scoped to the renderer process. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must be running Google Chrome prior to version 152.0.7977.65 on any supported desktop platform (Windows, macOS, or Linux). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 score is driven by the network delivery vector, low attack complexity, absence of required attacker privileges, and high C/I/A impact, making this appear as a high-priority issue on raw score alone. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a website and serves a crafted HTML page containing JavaScript designed to trigger a use-after-free condition in Chrome's V8 engine during object lifecycle transitions. A user running an unpatched Chrome version visits the page via a phishing email link, malicious advertisement, or compromised legitimate site, causing the renderer process to dereference freed memory and transfer control flow to attacker-supplied shellcode executing within the Chrome sandbox. … |
| Remediation | The primary remediation is updating Google Chrome to version 152.0.7977.65 or later, as confirmed by the vendor stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, verify Chrome's automatic update mechanism is enabled organization-wide and identify any systems running versions prior to 152.0.7977.65. …
