CVE-2026-11651 is a high-severity use-after-free vulnerability in the Network component of Google Chrome affecting versions prior to 149.0.7827.103. The flaw can be triggered by a remote attacker through a crafted HTML page, causing memory to be accessed after it has been freed. This memory-safety error can corrupt browser process state and enables arbitrary code execution within Chrome’s sandboxed context. The issue is classified as a network-reachable browser vulnerability with low attack complexity and requires user interaction to load attacker-controlled web content.
