Severity by source
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Network-delivered via crafted video requiring active user interaction (UI:R); no attacker privileges needed; C:H reflects renderer memory exposure; I:N and A:N as the flaw is read-only and no crash is described.

Out of bounds read in FFmpeg in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted video file. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds read in Chrome's bundled FFmpeg video decoding component (all versions prior to 150.0.7871.47) allows a remote attacker to leak renderer process memory contents via a crafted video file. The CVSS vector confirms network reachability with no required privileges (PR:N) but mandates user interaction (UI:R), meaning the victim must process the malicious video. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target user take an active step to process a crafted video - either by navigating to an attacker-controlled web page embedding the malicious video (including autoplay scenarios if autoplay is permitted) or by manually opening a downloaded video file in Chrome. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.5 (Medium) reflects genuine but bounded risk: network-reachable (AV:N), low complexity (AC:L), unauthenticated (PR:N), but gated by mandatory user interaction (UI:R) and limited to confidentiality (C:H, I:N, A:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious video file exploiting the FFmpeg boundary-check flaw and embeds it in a web page or sends it as a download link; when the victim opens the page or file in an unpatched Chrome instance and the video is decoded, the out-of-bounds read returns contents of adjacent renderer process memory - potentially including authentication tokens, page DOM data, or cached credentials - to the attacker. No public POC exists at time of analysis, but the attack vector (network-delivered media triggering a memory-safety bug in a codec parser) follows a well-understood exploitation pattern requiring only that the user visit the attacker's page. |
| Remediation | The primary remediation is to upgrade Google Chrome to version 150.0.7871.47 or later, as confirmed by the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html; this is a vendor-released patch and represents the complete fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
