Use-after-free in Google Chrome Network
CVE-2026-9873 is a critical use-after-free vulnerability in the Network component of Google Chrome prior to version 148.0.7778.216. The available reporting describes the flaw as occurring in Chrome’s core network architecture and being triggerable by a crafted HTML page. As a memory-safety bug, the issue arises when freed memory is subsequently reused, creating the possibility of attacker-controlled memory corruption during browser processing of malicious web content. Google has not publicly released detailed technical root-cause information or the specific vulnerable function at the time of disclosure, citing restricted bug details until most users are patched.
