Google Releases March Android Security Patches, Confirms Active Qualcomm 0‑Day

The updates arrive under Google’s revised cadence that prioritizes critical flaws monthly, with protection ultimately depending on each device maker’s rollout.

Overview

  • Google published two patch levels—2026-03-01 for AOSP components and 2026-03-05 for kernel and vendor drivers—closing well over a hundred vulnerabilities across framework, system and chipset code.
  • The bulletin flags limited in‑the‑wild exploitation of Qualcomm’s graphics/display flaw CVE-2026-21385, with Google and Qualcomm withholding specifics on impact and scope.
  • Critical risks include elevation‑of‑privilege and remote‑code‑execution issues such as CVE-2026-0047 in the framework and CVE-2026-0006 in system media components, some requiring no user interaction.
  • Google Play System (Mainline) updates deliver a dozen fixes this month, including mitigation for CVE-2026-0006, offering coverage for some devices that lack timely OEM patches.
  • Updates are only available for supported devices; Samsung has begun a March rollout addressing 65 vulnerabilities, while the separate Pixel device bulletin had not yet been posted.
