CVE	Date	Vulnerability	Products
CVE-2026-23761	Jan 22, 2026	VB-Audio Voicemeeter & Matrix BSoD via Driver FsContext invalidation (3.1.1.9) VB-Audio Voicemeeter, Voicemeeter Banana, and Voicemeeter Potato (versions ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 and earlier, respectively), as well as VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a vulnerability in their virtual audio drivers (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys, and vbaudio_vmvaio3*.sys). When a handle is opened with a special file attribute value, the drivers improperly initialize FILE_OBJECT->FsContext to a non-pointer magic value. If subsequent operations are not handled by the VB-Audio driver and are forwarded down the audio driver stack (e.g., via PortCls to ks.sys), the invalid FsContext value can be dereferenced, causing a kernel crash (BSoD), typically SYSTEM_SERVICE_EXCEPTION with STATUS_ACCESS_VIOLATION. This flaw allows a local unprivileged user to trigger a denial-of-service on affected Windows systems.	Twistedweb
CVE-2026-23762	Jan 22, 2026	VB-Audio Voicemeeter BSoD via Unprivileged Local DoS on Windows pre-1.1.1.9 VB-Audio Voicemeeter, Voicemeeter Banana, and Voicemeeter Potato (versions ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 and earlier, respectively), as well as VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a vulnerability in their virtual audio drivers (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys, and vbaudio_vmvaio3*.sys). The drivers map non-paged pool memory into user space via MmMapLockedPagesSpecifyCache using UserMode access without proper exception handling. If the mapping fails, such as when a process has exhausted available virtual address space, MmMapLockedPagesSpecifyCache raises an exception that is not caught, causing a kernel crash (BSoD), typically SYSTEM_SERVICE_EXCEPTION with STATUS_NO_MEMORY. This flaw allows a local unprivileged user to trigger a denial-of-service on affected Windows systems.	Twistedweb
CVE-2026-23763	Jan 22, 2026	LPE via vbmatrixvaio64 in VB-Audio Matrix1.0.2.2 & Matrix Coconut2.0.2.2 VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a local privilege escalation vulnerability in the VBMatrix VAIO virtual audio driver (vbmatrixvaio64*_win10.sys). The driver allocates a 128-byte non-paged pool buffer and, upon receiving IOCTL 0x222060, maps it into user space using an MDL and MmMapLockedPagesSpecifyCache. Because the allocation size is not page-aligned, the mapping exposes the entire 0x1000-byte kernel page containing the buffer plus adjacent non-paged pool allocations with read/write permissions. An unprivileged local attacker can open a device handle (using the required 0x800 attribute flag), invoke the IOCTL to obtain the mapping, and then read or modify live kernel objects and pointers present on that page. This enables bypass of KASLR, arbitrary kernel memory read/write within the exposed page, corruption of kernel objects, and escalation to SYSTEM.	Twistedweb
CVE-2026-23764	Jan 22, 2026	VB-Audio Voicemeeter & Matrix <3.x BSoD Local DoS via Driver VB-Audio Voicemeeter, Voicemeeter Banana, and Voicemeeter Potato (versions ending in 1.1.1.9, 2.1.1.9, and 3.1.1.9 and earlier, respectively), as well as VB-Audio Matrix and Matrix Coconut (versions ending in 1.0.2.2 and 2.0.2.2 and earlier, respectively), contain a vulnerability in their virtual audio drivers (vbvoicemeetervaio64*.sys, vbmatrixvaio64*.sys, vbaudio_vmauxvaio*.sys, vbaudio_vmvaio*.sys, and vbaudio_vmvaio3*.sys). The drivers allocate non-paged pool and map it into user space, where a length value associated with the allocation is exposed and can be modified by an unprivileged local attacker. On subsequent IOCTL handling, the corrupted length is used directly as the IoAllocateMdl length argument without adequate integrity checks before building and mapping the MDL, which can cause a kernel crash (BSoD), typically PAGE_FAULT_IN_NONPAGED_AREA. This flaw allows a local user to trigger a denial-of-service on affected Windows systems.	Twistedweb
CVE-2024-41810	Jul 29, 2024	Twisted XSS in util.redirectTo before 24.7.0rc1 Twisted is an event-based framework for internet applications, supporting Python 3.6+. The `twisted.web.util.redirectTo` function contains an HTML injection vulnerability. If application code allows an attacker to control the redirect URL this vulnerability may result in Reflected Cross-Site Scripting (XSS) in the redirect response HTML body. This vulnerability is fixed in 24.7.0rc1.	Twisted
CVE-2023-46137	Oct 25, 2023	Twisted <23.10.0rc1 twisted.web HTTP Pipeline Response Order RACE Twisted is an event-based framework for internet applications. Prior to version 23.10.0rc1, when sending multiple HTTP requests in one TCP packet, twisted.web will process the requests asynchronously without guaranteeing the response order. If one of the endpoints is controlled by an attacker, the attacker can delay the response on purpose to manipulate the response of the second request when a victim launched two requests using HTTP pipeline. Version 23.10.0rc1 contains a patch for this issue.	Twisted
CVE-2022-39348	Oct 26, 2022	Twisted <22.10.0rc1: Host Header Injection in 404 Response Twisted is an event-based framework for internet applications. Started with version 0.9.4, when the host header does not match a configured host `twisted.web.vhost.NameVirtualHost` will return a `NoResource` resource which renders the Host header unescaped into the 404 response allowing HTML and script injection. In practice this should be very difficult to exploit as being able to modify the Host header of a normal HTTP request implies that one is already in a privileged position. This issue was fixed in version 22.10.0rc1. There are no known workarounds.	Twisted
CVE-2022-24801	Apr 04, 2022	Twisted is an event-based framework for internet applications, supporting Python 3.6+ Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy.

CVE-2022-21716	Mar 03, 2022	Twisted is an event-based framework for internet applications, supporting Python 3.6+ Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds.	Twisted
CVE-2022-21712	Feb 07, 2022	twisted is an event-driven networking engine written in Python twisted is an event-driven networking engine written in Python. In affected versions twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twited.web.RedirectAgent` and `twisted.web. BrowserLikeRedirectAgent` functions. Users are advised to upgrade. There are no known workarounds.	Twisted
