After two ‘no security vulnerabilities’ bulletins in July and August, Google on Tuesday announced the release of patches for 180 vulnerabilities as part of the September 2026 Android security updates.
As usual, the updates are split into two parts. The first part arrives on devices as the 2026-09-01 security patch level and resolves 95 bugs across Android runtime, Framework, System, Setup Wizard, and multiple Project Mainline components (patched via Google Play system updates).
“The most severe of these issues is a critical security vulnerability in the System component that could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation,” Google notes in its advisory.
The security refresh addresses 56 security defects in the System component, including 23 critical-severity flaws that could lead to remote code execution (RCE), elevation of privilege (EoP), and denial-of-service (DoS).
The update also fixes 37 vulnerabilities in the Framework component, including three critical-severity bugs, and one flaw in Android runtime.
The second part of the update, the 2026-09-05 security patch level, contains fixes for 85 security defects across Android’s kernel and its components, as well as TV, Arm, Imagination Technologies, MediaTek, Tsingteng Micro, Unisoc, and Qualcomm components.
“Android’s September Bulletin is heavy in volume, containing a range of critical and high-severity patches. It’s worth noting that many of the critical severity updates are located in the System, which is responsible for most of a phone’s core functionality like app operation,” Jamf senior enterprise strategy manager Adam Boynton said.
“Most concerning from this list is CVE-2026-28662 because it’s a Wi-Fi-related memory corruption flaw. If left unpatched, it could enable attackers to execute code remotely, without any additional privileges or user interaction, potentially allowing privilege escalation. It’s crucial that organizations issue the updates across their device fleet as soon as possible,” Boynton added.
Devices updated to a security patch level of 2026-09-05 or newer contain patches for all these vulnerabilities, as well as for the flaws resolved with the previous Android patches.
There are no specific security patches for Wear OS, Android XR, and Android Automotive OS this month. Their updates, however, fix all the issues described in the September 2026 Android security bulletin.
