Analysis

AI-generated

Technical impact

A use‑after‑free flaw in Google Chrome for iOS enables a remote attacker to trigger heap corruption through a specially crafted HTML page. The vulnerability can lead to arbitrary memory reads or writes, which may ultimately allow arbitrary code execution on the device. The weakness is classified as CWE-416, a memory management error involving out‑of‑bounds access.

Affected Systems

Google Chrome on iOS is affected. All releases prior to version 147.0.7727.138 contain the flaw, so users running those builds are exposed.

Risk and Exploitability

The CVSS score is 8.8, EPSS score is < 1%, and the vulnerability is not listed in the CISA KEV catalog. The likely attack vector is inferred to be a malicious HTML page loaded within the browser, requiring no authentication or local privilege escalation. Because Chromium assigned a critical severity, the risk remains high until the patch is applied.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Google Chrome on iOS to version 147.0.7727.138 or newer.
  • Disable or restrict the execution of untrusted HTML content, for example by using content‑security‑policy settings or extensions that block external scripts, as a temporary measure.
  • Configure the iOS device to automatically install the latest Chrome updates and verify that the app’s update setting is enabled.
