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.

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 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.

Android March Security Update Patches Actively Exploited Qualcomm Display Zero-Day
Google’s March Android security update addressed **129 vulnerabilities**, including one **actively exploited** high-severity memory-corruption flaw in an open-source **Qualcomm display component** tracked as **CVE-2026-21385**. Google warned the issue “may be under limited, targeted exploitation,” and reporting indicated Qualcomm marked the vulnerability as exploited; Qualcomm stated it provided fixes to customers in **January 2026** and urged end users to apply OEM-delivered device updates as they become available. Separately, the Canadian Centre for Cyber Security issued multiple vendor rollups and advisories on March 2, 2026, including an **Android monthly rollup (AV26-187)** pointing organizations to the Android Security Bulletin for patching guidance. Additional Canadian advisories covered unrelated vulnerability sets in **Veeam Kasten for Kubernetes (AV26-188)**, **VMware Tanzu products (AV26-186)**, **Red Hat (including Linux kernel updates) (AV26-184)**, **CISA ICS advisories for multiple OT/IoT products (AV26-183)**, **Dell infrastructure products (AV26-181)**, and **IBM enterprise software (AV26-180)**; these are general patch-notification items and do not provide details tied to the Android/Qualcomm zero-day beyond directing readers to apply vendor updates.

Critical Zero-Click RCE Vulnerability (CVE-2025-48593) in Android System Component
Google released a security update in November 2025 to address a critical remote code execution vulnerability, CVE-2025-48593, in the Android System component. This flaw allows attackers to execute code remotely on affected devices running Android versions 13 through 16 without requiring user interaction or additional execution privileges. The vulnerability stems from insufficient validation of user input, making it possible for exploitation via a zero-click attack vector. The update also addressed a separate privilege escalation issue, CVE-2025-48581, affecting Android 16, but the primary concern is the zero-click RCE, which requires immediate patching due to its severity. Google has stated that there is no evidence of active exploitation in the wild at the time of the update. Security experts urge all users and organizations to apply the November 2025 security patch promptly to mitigate the risk posed by this critical vulnerability.
