Android December 2025 Security Update Addresses Critical DoS and Two Exploited Zero-Days
Google released the December 2025 Android Security Bulletin, patching 107 vulnerabilities, including a critical remote Denial of Service (DoS) flaw (CVE-2025-48631) in the Android Framework and two zero-day vulnerabilities (CVE-2025-48633 and CVE-2025-48572) that are reportedly under active exploitation. The zero-days allow for information disclosure and elevation of privilege, affecting Android versions 13 through 16, and are believed to be targeted in limited attacks. The DoS vulnerability enables remote attackers to crash or disable devices without requiring user interaction or additional execution privileges.
The update is distributed in two patch levels (2025-12-01 and 2025-12-05), covering both core Android components and vendor-specific issues. Google’s disclosure highlights the ongoing threat posed by actively exploited vulnerabilities in the Android ecosystem and underscores the importance of timely patching by device manufacturers and users. The December update represents one of the largest patch releases of the year, following a period of irregular vulnerability reporting from Google.

How this story unfolded
3 events from the most recent confirmed update back to the earliest known activity.
CISA adds the two Android Framework zero-days to the KEV catalog
After not appearing in CISA's Known Exploited Vulnerabilities catalog when Google published the bulletin, the two exploited Android Framework flaws were later added to KEV. Multiple follow-on reports on December 3 noted the KEV listing for CVE-2025-48633 and CVE-2025-48572.
Google says AOSP source patches will follow bulletin release
Google stated that source code for the vulnerabilities fixed in the December bulletin would be released to the Android Open Source Project repository within about 48 hours, by Wednesday after the bulletin's publication. This would make the fixes available to the broader Android ecosystem after the initial bulletin release.

Google Patches Android Zero-Interaction DoS and Zero-Click adbd RCE Flaws
Google issued Android security updates to fix multiple high-severity flaws, including **CVE-2026-0049**, a critical Android Framework vulnerability that can trigger a local denial-of-service with no user interaction and no elevated privileges, and **CVE-2026-0073**, a critical remote code execution bug in the Android System component tied to the Android Debug Bridge Daemon (`adbd`). The `adbd` flaw affects Android 14, 15, 16, and `16-qpr2`, and under proximal or adjacent network conditions could allow shell-level remote code execution on a target device without user action. The April bulletin also addressed **CVE-2025-48651**, a high-severity StrongBox issue affecting hardware-backed key storage implementations from Google, NXP, STMicroelectronics, and Thales, with fixes split between the `2026-04-01` and `2026-04-05` patch levels. Google said the `adbd` issue is remediated by the `2026-05-01` security patch level or later and noted that, because `adbd` is delivered through Project Mainline, mitigations can reach Android 10 and later devices faster through Google Play system updates; organizations were urged to accelerate deployment of the April and May patches across managed mobile fleets.

Google Patches Android Zero-Day and High-Severity XR Privilege Escalation Flaws
Google has issued its June 2026 Android security updates to fix **113 vulnerabilities**, including **18 critical** flaws and a zero-day tracked as `CVE-2025-48595` that the company said may be under limited, targeted exploitation. The zero-day affects the **Android Framework** and stems from an integer overflow memory-management issue that can enable code execution and potentially full device compromise. The update also addresses vulnerabilities in third-party components from **Qualcomm, MediaTek, and Unisoc**, and Google said devices running Android 10 or later can receive relevant fixes through Google Play services, with patch levels dated **2026-06-05** or later remediating the documented issues. Google also published its June 2026 **XR Security Bulletin**, disclosing a high-severity flaw, `CVE-2026-0072`, in `InputMethodManagerService`. The bug is caused by a missing permission check in `addInputMethodListener` and can allow **local elevation of privilege** without additional execution privileges or user interaction; Google said it could also permit input text to be read without permission. The XR issue is fixed with security patch level **2026-06-01** or later, while full XR protection requires the broader Android June 2026 patch level as well, underscoring the need for enterprises to accelerate deployment of both platform and device-vendor updates.

Google March Android Security Bulletin Patches 129 Flaws Including Actively Exploited Qualcomm Display Zero-Day
Google released the March 2026 *Android Security Bulletin*, issuing fixes for **129 vulnerabilities** across the Android ecosystem and shipping two patch levels (`2026-03-01` and `2026-03-05`) to help OEMs stage platform and hardware-specific updates. The most urgent issue is **CVE-2026-21385**, a **high-severity, actively exploited** zero-day in an open-source **Qualcomm display** component used in Android devices with affected Qualcomm/Snapdragon chipsets. Reporting indicates CVE-2026-21385 is a **memory-corruption** flaw caused by an **integer overflow/wraparound** condition that can lead to memory corruption during allocation/alignment in display drivers; successful exploitation could enable device compromise (e.g., arbitrary code execution and/or privilege escalation) and bypass security boundaries. Google and Qualcomm both acknowledged **limited, targeted exploitation in the wild**, and one account attributes discovery/confirmation of exploitation to Google’s **Threat Analysis Group (TAG)**; devices not updated to at least patch level `2026-03-05` remain exposed, making rapid patch deployment and user update compliance the primary risk-reduction actions.
