Windows Ancillary Function Driver for WinSock Elevation of Privilege Vulnerability

Access of resource using incompatible type ('type confusion') in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally.

Heap corruption via duplicate masterKey fields in MongoDB libmongocrypt

Improper state management in MongoDB libmongocrypt can cause provider-specific data to be treated as an incompatible type when cleaning up a key document containing duplicate masterKey fields. An authenticated actor who can modify key vault documents, or a server that returns such a key document, can cause invalid memory access and invalid frees in the client process. This can terminate the application or corrupt process memory.

Objenesis before 3.6 Type Confusion via Class Name Instantiator Cache

Objenesis before 3.6 contains a type confusion vulnerability that allows code in one class loader to substitute objects into another by exploiting instantiator caching keyed on class name. When a shared ObjenesisStd instance caches instantiators by clazz.getName() in ObjenesisBase.getInstantiatorOf(), same-named classes collide, causing newInstance() to return wrong-class objects and ClassCastException failures.

Wasmtime: Bit-packing in Cranelift compiler causes silent overflow and miscompilation

Wasmtime is a runtime for WebAssembly. Prior to 36.0.19 and 43.0.0, the Cranelift compiler backend bit-packs SSA value indices in a way that can silently overflow in release builds when compiling a sufficiently large or specially crafted Wasm function with many SSA values. The overflow can make Cranelift reference incorrect IR values, causing arbitrary miscompilation, type confusion, and other attacker-controlled effects that may escape the Wasm sandbox on any architecture using the default Cranelift backend. This issue is fixed in versions 36.0.19 and 43.0.0.

Lean 4 Kernel Type Checking Bypass via Mismatched Structure Projections

The Lean 4 kernel does not verify that the structure named in a projection expression matches the type of the value being projected, and environment::add_inductive in src/kernel/inductive.cpp did not type check the nested inductive applications that are replaced by auxiliary types, so their parametric arguments escaped checking. A metaprogram running in the Lean process can register an ill-typed nested inductive whose constructor applies a .proj C 0 projection to a value of the unrelated type W, and the kernel admits the declaration through the ordinary checked addDecl path at maximum kernel checking, without sorry, unsafeCast, debug.skipKernelTC, addDeclWithoutChecking, FFI, or a modified .olean file. The result is a type confusion yielding a proof of False that carries no axioms, from which any proposition can be derived. The published proof of concept additionally pads two expressions until their hashes and approximate depths collide, which defeats kernel caching; that is the technique used to reach the flaw, not its cause. Exploitation requires running a metaprogram in-process, for example by building a project or importing a malicious Lake dependency.

Type confusion in V8 in Google Chrome prior to 152.0.7977.82 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High)

Access of resource using incompatible type ('type confusion') vulnerability in Samsung Open Source Escargot allows Pointer Manipulation. This issue affects Escargot: before 779f6bedf58f334dec64b0a51ebb724b4708b84a.

Desktop Window Manager Elevation of Privilege Vulnerability

Access of resource using incompatible type ('type confusion') in Desktop Window Manager allows an authorized attacker to elevate privileges locally.

Windows Secure Kernel Mode Information Disclosure Vulnerability

Access of resource using incompatible type ('type confusion') in Windows Secure Kernel Mode allows an authorized attacker to disclose information locally.

Windows CD-ROM Driver Elevation of Privilege Vulnerability

Access of resource using incompatible type ('type confusion') in Windows CD-ROM Driver allows an authorized attacker to elevate privileges locally.

Dashy: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)

Dashy is a self-hostable personal dashboard. From 1.9.4 until 3.2.0, the Dashy RSS Widget in src/components/Widgets/RssFeed.vue does not sanitize RSS item link values before rendering feed item titles and Read More links as anchor href attributes, allowing an attacker-controlled feed to provide a javascript: URI that executes when clicked in the Dashy origin. This issue is fixed in version 3.2.0.

Type Confusion Vulnerability Can Cause Unexpected System Termination

A type confusion issue was addressed with improved memory handling. This issue is fixed in macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6. An app may be able to cause unexpected system termination.

Windows StateRepository API Elevation of Privilege Vulnerability

Access of resource using incompatible type ('type confusion') in Windows StateRepository API allows an authorized attacker to elevate privileges locally.

RPC Runtime Remote Code Execution Vulnerability

Access of resource using incompatible type ('type confusion') in RPC Runtime allows an unauthorized attacker to execute code over a network.

Windows Domain Name Service Remote Code Execution Vulnerability

Access of resource using incompatible type ('type confusion') in DNS Server allows an unauthorized attacker to execute code over a network.

Windows DNS Denial of Service Vulnerability

Improper enforcement of behavioral workflow in Windows DNS allows an unauthorized attacker to deny service over a network.

VMX: VMentry failure with branch tracing and blocked states

For XSA-308 logic was introduced, as VMX VMEntry checks do not like the exact combination of state which occurs when #DB in intercepted, Single Stepping is active, and blocked by STI/MovSS is active, despite this being a legitimate state to be in. The resulting VMEntry failure is fatal to the guest. Sadly there is another special sub-case of the above, with branch tracing enabled. In that case the prior adjustment would still cause a VMentry failure, as before fatal to the guest.

Vyper 0.3.8 through 0.5.0b1 Memory Misread via Ternary Nested Array Selection

Vyper 0.3.8 through 0.5.0b1 contains a compiler miscompilation vulnerability in parse_IfExp that reads nested arrays with narrower inner bounds using the wider result type's memory layout. When a ternary selects the narrower array, inner arrays after the first are read at wrong offsets, causing contracts to silently store corrupted values or revert.

FileRise: Session-scoped TOTP rate limiting permits repeated verification attempts

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise stores failed TOTP verification attempts in $_SESSION. An attacker who already possesses a target account's valid primary credential can restart the login workflow in a new session and restore the second-factor attempt allowance, permitting continued online TOTP guessing beyond the intended five-attempt limit. The pending-login TOTP handlers did not share a durable account-wide limit. This issue is fixed in version 3.23.0.

Seroval: `seroval.fromJSON()` Promise resolver type confusion invokes attacker-controlled methods during deserialization

Seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. Prior to 1.5.3, seroval.fromJSON() allows attacker-controlled JSON Promise control nodes to operate on values from the general deserialization reference table without verifying genuine internal Promise resolver records, causing deserialization side effects with plugins enabled and potentially unintended server-side invocation or remote code execution when downstream frameworks register callable wrappers. This issue is fixed in version 1.5.3.
