Security readout for executives and security teams
Plain-English summary
A malicious webpage could exploit a memory-safety flaw in Chrome on macOS to run attacker-controlled code beyond the browser sandbox. The supplied description identifies versions before 152.0.7977.65 as vulnerable. Successful exploitation requires a user to open crafted web content.
Executive priority
Treat this as an urgent browser update because malicious web content could achieve code execution outside Chrome's sandbox. Accelerate macOS fleet patching and verify completion, while avoiding claims of active exploitation unsupported by the supplied sources.
Technical view
CVE-2026-79150 is a use-after-free vulnerability in Chromium Views, classified as CWE-416. It is remotely reachable through crafted HTML, requires user interaction, and can cross a security boundary to affect confidentiality, integrity, and availability.
Likely exposure
Exposure is limited by the supplied evidence to Google Chrome on macOS before 152.0.7977.65. Risk is greatest where users browse untrusted sites, follow external links, or operate with delayed browser updates. Other operating systems and Chromium-based products are not established as affected by this bundle.
Exploitation context
The CVSS 3.1 score is 9.6, reflecting low attack complexity, no required privileges, user interaction, and potential sandbox escape. The CVE is not listed as KEV in the supplied bundle, and no cited evidence establishes active exploitation.
Researcher notes
The structured affected entry lists 152.0.7977.65, while the narrative says versions prior to that release are affected; this analysis treats it as the fixed boundary. Public issue details may be restricted or incomplete. No exploit availability, attack campaign, or broader Chromium-product impact is established here.
Mitigation direction
- Update Chrome on macOS to 152.0.7977.65 or later.
- Restart Chrome after updating so the corrected version is active.
- Prioritize managed devices with outdated Chrome installations.
- Consult Google guidance if updating is temporarily impossible.
Validation and detection
- Inventory Chrome versions across all managed macOS devices.
- Confirm every installation reports version 152.0.7977.65 or later.
- Verify browsers restarted after the update was installed.
- Monitor endpoint and browser telemetry for unexpected Chrome child processes or security alerts.
