AI Analysis

Impact

The vulnerability is a use‑after‑free flaw in Chrome’s media handling that permits a remote attacker to inject and execute arbitrary code within the sandbox by serving a malicious HTML page. Because the flaw triggers when Chrome processes media content, any untrusted web content could exploit it, potentially compromising the user’s data or local system. The weakness is classified as CWE‑416, signifying a misuse of a freed memory object.

Affected Systems

Users running Google Chrome prior to the 155.0.8059.79 stable release are affected. The flaw has been fixed in subsequent Chrome updates; any installation older than that version remains vulnerable.

Risk and Exploitability

With a CVSS score of 8.8, the issue is of high severity, yet its EPSS score is under 1%, indicating a low immediate exploitation probability. It is currently not listed in the CISA KEV catalog. The required attack vector is remote: a crafted web page must be loaded in the browser. The vulnerability enables code execution inside the sandboxed context, preventing immediate escape but still allowing local compromise.

OpenCVE Recommended Actions

  • Update Chrome to 155.0.8059.79 or newer, which resolves the memory safety bug.
  • If an immediate update is not feasible, block or disable vulnerable media features to mitigate exposure.
  • Enforce stricter browser security settings, such as Content Security Policy or Site Isolation, to reduce the risk of exploitation by sandboxed content.
