AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Network-delivered via crafted page (AV:N) with no privileges (PR:N) but requiring victim UI gestures (UI:R); heap-corruption-to-RCE justifies C/I/A:H, though 'specific gestures' arguably approaches AC:H.

Use after free in SignIn in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Use-after-free in Google Chrome's SignIn component (versions prior to 150.0.7871.47) allows a remote attacker to trigger heap corruption and potentially achieve code execution after luring a victim to a crafted HTML page and performing specific UI gestures. No public exploit was identified at time of analysis, and with an EPSS of 0.17% (7th percentile) and Chromium-rated 'Low' severity, near-term mass exploitation appears unlikely despite the high 8.8 CVSS. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to load an attacker-crafted HTML page AND to perform specific UI gestures that drive the vulnerable SignIn/account flow - the description explicitly conditions the bug on the user being convinced 'to engage in specific UI gestures,' which is a stronger prerequisite than the generic UI:R in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals here are notably in tension. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page and, via social engineering (phishing link, malvertising), lures a Chrome user to it and prompts them into the specific UI gestures involving the sign-in flow that trigger the use-after-free. The freed SignIn object is reclaimed with attacker-controlled heap data, corrupting memory in an attempt to hijack control flow within the browser process. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the Chrome Releases Stable channel update (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
