PDFium in Google Chrome prior to 54.0.2840.59 for Windows, Mac, and Linux; 54.0.2840.85 for Android incorrectly handled object lifecycles in CFFL_FormFillter::KillFocusForAnnot, which allowed a remote attacker to potentially exploit heap corruption via crafted PDF files.

Security readout for executives and security teams

This is an old Google Chrome PDF handling flaw. A malicious PDF could trigger heap corruption in PDFium on affected Chrome versions. The main business risk is legacy or unmanaged browsers still able to open untrusted PDFs. Current evidence does not show active exploitation in CISA KEV. Most modern environments should not be exposed if Chrome or Chromium packages are routinely updated. Exposure is plausible on legacy endpoints, frozen virtual desktop images, unmanaged Android devices, or old Linux distribution packages still running affected Chrome builds. Prioritize this as a legacy exposure check, not a current emergency, unless affected Chrome versions are found. If old browsers remain in production, remediate quickly because the vulnerable component processes attacker-supplied PDF content. Mitigation focus: Update Chrome beyond 54.0.2840.59 on Windows, Mac, and Linux.; Update Android Chrome beyond 54.0.2840.85.; Apply Red Hat or Gentoo Chromium security updates where applicable..
