Out of bounds read in SurfaceCapture in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds memory read in the SurfaceCapture component of Google Chrome before 150.0.7871.47 lets a remote attacker leak adjacent heap memory when a victim opens a crafted HTML page. Chromium rated the flaw Medium severity, though the associated CVSS is 8.1; there is no public exploit identified at time of analysis and EPSS estimates exploitation probability at just 0.17% (7th percentile), consistent with a browser bug fixed pre-disclosure. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively open or render attacker-controlled HTML in a vulnerable Chrome build (CVSS UI:R) - it is not zero-click. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict and should be weighed carefully. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page (or serves it via a malvertising/compromised-site iframe) that supplies crafted parameters to the SurfaceCapture path. When a victim simply visits the page, the browser reads out-of-bounds heap memory, and the leaked bytes are exfiltrated back to the attacker or used to weaken sandbox/ASLR defenses in a follow-on exploit chain. … |
| Remediation | Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the built-in updater (chrome://settings/help) and relaunch the browser; managed fleets should push the update through their enterprise deployment channel per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
