Microsoft has fixed 2,760 vulnerabilities in 2026, more than double last year's total, which ZDI's Dustin Childs attributes to AI-assisted discovery becoming the 'new normal'.
Heap-Based Buffer Overflow in Windows ALPC Enables Local Privilege Escalation
CVE-2026-85880 is a heap-based buffer overflow in Windows Advanced Local Procedure Call (ALPC), the Windows mechanism for local inter-process communication. An authorized local attacker can trigger the overflow by submitting crafted input over ALPC, corrupting heap memory in the component that handles the request. Successful exploitation allows the attacker to execute code with elevated privileges, typically gaining SYSTEM-level control of the local host, which is especially valuable as a post-exploitation or sandbox-escape step. Affected products include Windows 10 (1607, 1809, 21H2, 22H2) and Windows Server 2012, 2016, 2019, and 2022, meaning most on-premises Windows estates are in scope. The flaw was fixed in Microsoft's record 974-CVE September 2026 Patch Tuesday and was added to CISA's KEV on 2026-09-08, confirming exploitation in the wild; press reports describe Windows zero-days being chained with a Chrome zero-day in 'BlueMoon' kit attacks, though the data does not explicitly confirm this CVE is the Windows flaw in that chain.

Local Privilege Escalation via Link Following in Windows Update Stack
CVE-2026-81963 is a link-following flaw (CWE-59, improper link resolution before file access) in the Microsoft Windows Update Stack, in which the component fails to correctly resolve file links before opening them. A local attacker with low privileges can plant or manipulate a link (symlink/junction) that the privileged update stack follows during operation, redirecting its file access to an attacker-controlled target. The result is local privilege escalation — CVSS 3.1 rates this 7.8 (high) with high confidentiality, integrity, and availability impact — allowing an authorized local user or malware already on the machine to gain elevated rights. Affected products are Windows 11 23H2, 24H2, 25H2, and 26H1 and Windows Server 2025; any unpatched system on those versions is exposed to any local account holder. The flaw was fixed in Microsoft's record September 2026 Patch Tuesday (974 CVEs), was added to CISA's KEV on 2026-09-08 as one of two Windows zero-days reported as exploited in the wild, and has no known public PoC or confirmed ransomware use.

Heap Buffer Overflow in Windows Win32K Enables Local Privilege Escalation
CVE-2026-62712 is a heap-based buffer overflow (CWE-122) in the Windows Win32K kernel component, with Microsoft's related advisories (ZDI-26-542/618/619/620/621) tying the flaw to user-mode printer driver (UMPD) graphics callbacks such as UMPDDrvBitBlt, UMPDDrvStretchBlt and UMPDDrvRealizeBrush. A local attacker with valid low-privileged credentials can trigger the overflow through crafted GDI/printer-driver operations, with no user interaction required. Successful exploitation elevates the attacker from a standard user to kernel/SYSTEM level, yielding high confidentiality, integrity and availability impact on the host. Every Windows 10 (1607, 1809, 21H2, 22H2), Windows 11 (23H2 through 26H1) and Windows Server (2012, 2016, 2019, 2022) installation on the listed builds is affected, which spans most of the supported Windows fleet. There is no public proof-of-concept, no CISA KEV listing, and a low EPSS of 0.4%, indicating no confirmed exploitation to date.

Pre-auth use-after-free RCE in Microsoft Windows Deployment Services (WDS)
Microsoft Windows Deployment Services (WDS) contains a use-after-free memory-safety flaw (CWE-416) that an unauthenticated attacker can trigger by sending crafted network traffic to the WDS service, leading to remote code execution on the target system. The vulnerability affects Windows 10 1607 and 1809 and Windows Server 2012, 2016, 2019, 2022, and 2025 on systems where WDS is deployed, a role typically used for network-based (PXE) operating system imaging. A successful exploit grants the attacker code execution with high confidentiality, integrity, and availability impact, reflected in the critical CVSS 3.1 score of 9.8 with network vector, low complexity, and no privileges or user interaction required. No public proof-of-concept, CISA KEV listing, or confirmed in-the-wild exploitation is currently known, although EPSS estimates a 2.7% probability of exploitation within 30 days (85th percentile). The flaw was disclosed alongside Microsoft's record September 2026 Patch Tuesday, which shipped nearly 1,000 fixes including two Windows zero-days.

Unbootable-System Denial of Service via Link Following in Backblaze Windows Backup Client
CVE-2026-19820 is a link-following flaw (CWE-59) in the Backblaze Personal Computer Backup client for Windows, whose backup components (bzserv, bztransmit, bzfilelist, bzbackup, and bzreports) do not properly resolve links in the folders they traverse. A local user can create a link from Backblaze's folder to Windows OS system files during a backup; when the client follows the link, the affected machine can be rendered unbootable. Successful exploitation requires that an administrator-level system change has removed the specific Windows OS security controls that normally govern link resolution, allowing the link to be planted in this way. The impact is loss of availability of the whole system (high impact on the system's ability to boot), not data theft. Exploitation is not currently known: no public PoC exists, the flaw is not in CISA's KEV catalog, and EPSS puts 30-day exploitation probability at about 0.3%.

Actively Exploited V8 Type Confusion in Google Chrome (CVE-2026-85046)
Google Chrome versions prior to 152.0.7977.82 contain a type confusion flaw (CWE-843) in the V8 JavaScript engine, which mishandles object types during engine operations (public proof-of-concept writeups indicate it is reachable through array sorting and WebAssembly-related code paths). A remote attacker triggers the flaw simply by getting a user to open a crafted HTML page, with no privileges or authentication required. Successful exploitation lets the attacker execute arbitrary code inside the browser's sandbox, and public reporting shows it being chained with Windows zero-days (the 'BlueMoon' exploit kit) by Chinese espionage groups for broader compromise. Any user of an unpatched Chrome or another build embedding the affected V8 engine is exposed. The vulnerability is a zero-day that was actively exploited in the wild before patching, was added to CISA's KEV on 2026-09-04, and has five public proof-of-concept references.

CVE-2026-60413 is a vulnerability in the Outside In Core component of Oracle Outside In Technology 8.5.8, Oracle's document parsing and conversion engine that is bundled within Oracle Fusion Middleware. An unauthenticated attacker who can log on to the infrastructure where Outside In Technology executes (CVSS attack vector AV:L, no privileges required) can trigger the flaw, and successful attacks require interaction from a user other than the attacker — consistent with a crafted file being submitted for parsing. The related ZDI advisory (ZDI-26-637) characterizes the issue as an integer overflow when parsing GEM files that can lead to remote code execution, while Oracle's entry maps the weakness to CWE-200 and rates it 7.8 (high) with high confidentiality, integrity, and availability impacts, resulting in takeover of Outside In Technology. Any deployment running the affected 8.5.8 release of Outside In Technology — typically embedded inside Oracle Fusion Middleware or other products that use the engine for document conversion — is affected. There is currently no public proof-of-concept, the issue is not in CISA KEV, and EPSS estimates only a 0.2% probability of exploitation within 30 days, so no exploitation is known.

Heap Buffer Overflow in Microsoft Windows Codecs Library Enables Local Code Execution
CVE-2026-58599 is a heap-based buffer overflow (CWE-122) in the Microsoft Windows Codecs Library, patched by Microsoft as part of the September 2026 Patch Tuesday. The CVSS vector (AV:L, UI:R, no privileges required) indicates the flaw is triggered locally when the codecs library processes specially crafted content, requiring user interaction such as opening a malicious media or image file. A successful attacker can execute arbitrary code in the context of the local user with no prior privileges, with high impact on confidentiality, integrity, and availability. Any Windows system containing the affected Windows Codecs Library is exposed, though the source data does not enumerate specific Windows versions or builds. Exploitation is currently quiet: there is no public proof-of-concept, no CISA KEV listing, and EPSS estimates only about a 0.3% probability of exploitation within 30 days (25th percentile).
