Analysis

Impact

A use- after- free networking stack to send specially crafted QUIC packets that trigger heap corruption in the browser process, potentially leading to arbitrary code execution or denial of service if the corruption is successfully leveraged.

Affected Systems

All desktop installations of Google Chrome prior to version 150.0.7871.47 are operating system; Windows, macOS, and Linux are mentioned by the vendor, but the vulnerability exists in all platforms where Chrome runs.

Risk and Exploitability

The CVSS score is 8.1, indicating a high-severity vulnerability less than 1 %, reflecting a low probability of widespread exploitation, and the issue is not listed in the CISA KEV catalog. Exploitation requires a remote attacker to target the vulnerable browser with crafted QUIC traffic, and no privilege escalation or user interaction is needed to initiate the attack, but practical exploitation would likely require significant expertise due to the complexity of inducing a heap corruption.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade to Google Chrome version 150.0.7871.47 or newer, which removes the use- after- free flaw.
Enable automatic Chrome updates to receive future security patches without manual intervention.
If an update cannot be applied immediately, disable QUIC in Chrome by setting "chrome://flags/#enable-quic" to "Disabled" or block QUIC traffic over its standard ports (443 and 8443) using network filtering to prevent malicious packet delivery.
