AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N
AC:H reflects mandatory prior renderer compromise; UI:R for crafted page; C:H for memory disclosure; I:N/A:N as only confidentiality is impacted with no scope change.

Out of bounds read in Chromecast in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds read in the Chromecast component of Google Chrome prior to 150.0.7871.47 enables a remote attacker, who has already achieved renderer process compromise, to exfiltrate potentially sensitive data from process memory via a crafted HTML page. This is a second-stage, chained vulnerability - it cannot be exploited in isolation and requires a prior renderer compromise as a prerequisite. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two explicit prerequisites: (1) the attacker must have already achieved compromise of the Chrome renderer process via a separate, unrelated vulnerability - this is confirmed by the description and reflected in CVSS AC:H; and (2) the victim must load a crafted HTML page (CVSS UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.3 (Medium) is consistent with the realistic attack complexity here. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has independently compromised the Chrome renderer process - for example, via a separate renderer RCE vulnerability - then serves a crafted HTML page that triggers the Chromecast component's out-of-bounds read, causing it to read beyond an allocated buffer and return memory contents to the attacker. The leaked data could include sensitive in-memory artifacts such as authentication tokens, encryption keys, or user credentials present in renderer memory at the time of exploitation. … |
| Remediation | The primary fix is to update Google Chrome to version 150.0.7871.47 or later, as documented in the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
