Chrome is widely deployed; this is a sandbox escape allowing arbitrary code execution outside the renderer, posing enterprise-wide risk if unpatched.
CVE-2026-87537
Chrome sandbox escape enabling code execution outside renderer via crafted network traffic
Is CVE-2026-87537 being exploited?

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
