A vulnerability has been identified in Solid Edge SE2025 (All versions < V225.0 Update 15), Solid Edge SE2026 (All versions < V226.0 Update 7). The affected applications contain a use-after-free vulnerability that could be triggered while parsing specially crafted DFT files. This could allow an attacker to execute code in the context of the current process.

Ruby JSON is a JSON implementation for Ruby. From 2.20.0 until 2.21.2, Ruby's JSON native C extension clears the consumed JSON::ResumableParser input buffer but leaves state.start, state.cursor, and state.end pointing into released storage. When partial_value reconstructs an incomplete object containing duplicate keys, the duplicate-key warning path calls cursor_position, which dereferences those stale pointers. This results in a heap-use-after-free and can terminate the Ruby process. An attacker who can supply JSON stream data to an application using JSON::ResumableParser may cause process termination when the application calls partial_value on incomplete attacker-controlled input containing duplicate object keys. This issue has been fixed in version 2.21.2.

llama.cpp builds b7492 through the latest b9060 contains a use-after-free vulnerability in llama-server affecting six tokenization endpoints (/tokenize, /detokenize, /infill, /apply-template, /rerank, and /anthropic/count_tokens) that bypass the task queue and access ctx_server.vocab directly on HTTP worker threads. Attackers can exploit a time-of-check-time-of-use race condition where the main thread destroys and frees vocab after the synchronization lock is released but before the handler finishes using it, causing a crash or potential code execution when --sleep-idle-seconds is configured.

llama.cpp builds b7492 through the latest b9060 contains a use-after-free vulnerability in the vocab pointer of llama-server when the --sleep-idle-seconds feature is enabled, allowing unauthenticated remote attackers to execute arbitrary code. Attackers can trigger the vulnerability by sending requests to affected endpoints while the server transitions to sleep mode, causing concurrent worker threads to dereference a freed vocab pointer that can be reclaimed with attacker-controlled data to achieve remote code execution.

A maliciously crafted PDF file, when parsed through Autodesk Revit, can force a Use-After-Free vulnerability. A malicious actor can leverage this vulnerability to cause a crash, disclose sensitive data, or execute arbitrary code in the context of the current process.

Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers.

CVE-2026-56848 is a high-severity use-after-free vulnerability in Node.js HTTP/2 handling. It occurs when the function nghttp2_session_mem_send() is called re-entrantly during the execution of nghttp2_session_mem_recv(), leading to a heap-use-after-free condition. This flaw affects specific Node.js versions 26.5.0, 24.18.0, and 22.23.1. The vulnerability does not impact confidentiality or integrity but can cause denial of service due to application crashes. There is no confirmed patch or official remediation available at this time.

Use after free in Microsoft Office Excel allows an unauthorized attacker to execute code over a network.
