Use-after-free in Google Chrome Bluetooth on Mac

IdentifiersCVE-2026-13035CWE-416

CVE-2026-13035 is a high-severity use-after-free vulnerability in the Bluetooth component of Google Chrome on macOS. According to the provided content, the flaw affects Google Chrome on Mac prior to version 149.0.7827.197 and can be triggered by a malicious Bluetooth peripheral. The vulnerability arises from incorrect memory lifetime handling in the Bluetooth component, where freed memory may be subsequently reused, creating a condition that can lead to memory corruption and attacker-controlled execution flow. The available advisories do not identify the specific vulnerable function or code path, but they consistently characterize the issue as a use-after-free in Bluetooth with remote code execution potential.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation may allow a remote attacker to execute arbitrary code on an affected macOS system. Depending on the resulting execution context, this could enable compromise of the browser process, further post-exploitation activity within the browser security model, application instability, or a crash/denial of service. Debian’s broader Chromium advisory also notes that vulnerabilities in this release family could result in arbitrary code execution, denial of service, or information disclosure, although the specific content for CVE-2026-13035 most directly supports arbitrary code execution via a malicious peripheral.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by disabling Bluetooth when not required, avoiding pairing or interacting with untrusted Bluetooth devices/peripherals, and restricting physical proximity opportunities for rogue peripherals. Enterprise defenders can also limit use of Bluetooth peripherals on sensitive macOS endpoints until the patched Chrome version is deployed. No specific vendor workaround beyond updating was provided in the supplied advisories.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome on macOS to version 149.0.7827.197 or later. For Chromium-based distributions, apply the vendor-supplied patched release; the provided Debian advisory references chromium version 149.0.7827.196-1~deb13u1 or later patched package versions. Standard remediation is to deploy the official browser update containing Google’s fix for CVE-2026-13035.
