Race condition in Zephyr RTOS's I3C IBI workqueue subsystem allows a physically-present attacker controlling an I3C peripheral to corrupt kernel memory structures, most realistically causing denial of service. The unsynchronized free-list (sys_slist_t) shared between ISR context and the workqueue handler thread creates a window where a work node can be handed to two consumers simultaneously or a garbage pointer can be dereferenced in a memcpy, producing an out-of-bounds write. No public exploit code has been identified and no CISA KEV listing exists; the patch wrapping all free-list operations in a k_spinlock is confirmed in upstream commit e87e7e2.
Race condition exploitation in FileCodeBox's Pickup Limit Handler allows remote unauthenticated attackers to bypass configured file download quotas by sending concurrent retrieval requests. The flaw exists in the `update_file_usage` function (`apps/base/views.py`) across all releases prior to v2.5.0 - including v2.4.0 despite the CVE description citing only 'up to 2.3'. A public proof-of-concept is available via GitHub issue #482, though no active exploitation has been confirmed by CISA KEV. The vendor-released fix is confirmed in v2.5.0 via commit 8d7d856.
Race condition in macrozheng mall's /order/submit endpoint (versions up to 1.0.3) allows authenticated remote attackers to exploit unsynchronized order state through concurrent HTTP request timing. The CVSS 4.0 vector (AV:N/AC:H/PR:L) confirms network reachability but high attack complexity and a required authenticated session, yielding limited integrity and availability impact. No public exploit code has been identified and the vendor deleted the associated GitHub issue without explanation, reducing transparency around scope and remediation.
Authentication denial of service in free5GC AUSF v1.4.4 and current main allows an attacker with access to the AUSF SBI/N12 interface to permanently block a target subscriber from completing 5G authentication by flooding the AUSF with concurrent POST /nausf-auth/v1/ue-authentications requests for the same SUPI. Each concurrent request silently overwrites the active EAP-AKA' session context stored under that SUPI key, so the legitimate UE's EAP response is validated against mismatched cryptographic material (K_aut, XRES) and fails AT_MAC verification. No vendor patch has been released; a working proof-of-concept was reproduced in a controlled lab and is documented in the upstream GHSA advisory, with no CISA KEV listing identified at time of analysis.
Race condition in multer's file stream handling allows uploaded files exceeding the configured fileSize limit to bypass size-limit rejection when an application uses an asynchronous fileFilter in combination with the fileSize limit. All multer versions before 2.3.0 are affected. Practical impact is constrained because the underlying busboy multipart parser still truncates the stream at the configured limit, making this a logic bypass of the rejection mechanism rather than uncontrolled resource consumption or data exfiltration; the fix is available in multer 2.3.0.
Copilot Chat in Microsoft Edge (Chromium-based) exposes a race condition that enables an authorized, low-privileged attacker to disclose information across a component scope boundary over the network. The flaw arises from improper synchronization of concurrent access to a shared resource within the Copilot Chat feature, producing partial confidentiality and, per the official CVSS vector, limited integrity exposure. No public exploit code has been identified at time of analysis, and this vulnerability does not appear in the CISA Known Exploited Vulnerabilities catalog.
Cross-user data disclosure in SvelteKit (npm/@sveltejs/kit versions 2.38.0 through 2.60.0) stems from a race condition in the query.batch() API that can cause concurrent HTTP requests from different authenticated users to merge under a single shared request context. Successful exploitation allows one user to receive response data belonging to another user's simultaneous session, including potentially sensitive application state. Vendor-released patch version 2.60.1 is available; no active exploitation has been confirmed and no public exploit code has been identified at time of analysis.
Spring Integration's reactive message pipeline leaks reply routing and security headers across concurrent users when an IntegrationFlow uses .fluxTransform() with an asynchronous or reordering operator that emits raw payloads, causing one user's replyChannel, correlationId, and security or tenant headers to be applied to another concurrent user's response. Affected versions span the 5.5.x, 6.4.x, 6.5.x, 7.0.x, and 7.1.0 release lines across the core Spring Integration library, as confirmed by VMware via the spring.io security advisory. The CVSS 8.2 score reflects network exploitability with no authentication required and high confidentiality impact; no public exploit has been identified at time of analysis.
Concurrent message processing in Spring Integration's script-backed channels causes shared ScriptEngine state corruption when using JSR-223 engines that declare THREADING=null, such as the Kotlin KTS engine. Affected Spring Integration versions from 5.5.21 and earlier through 7.1.0 are susceptible to cross-message data leakage, where one message's payload or header bindings can bleed into another message's script evaluation context under concurrent load. No public exploit has been identified at time of analysis, and the CVSS 4.2 Medium rating reflects the high attack complexity imposed by the required race condition, though the information disclosure and partial integrity impact are real concerns in multi-tenant or high-throughput deployments.
Null pointer dereference in ccoap (commit 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5) allows remote unauthenticated attackers to crash the CoAP server by submitting requests that trigger a race condition between the session dispatch and cleanup threads. The impact is confined to availability - the server process crashes, producing a denial-of-service condition with no confidentiality or integrity consequences. No active exploitation is confirmed (not in CISA KEV), and an EPSS score of 0.17% (7th percentile) places this in the lowest tier of current exploitation likelihood.
