Denial of service in NASA-JPL ION-DTN before 4.2.1-a.1 allows unauthenticated remote attackers to crash the ION process by sending a single crafted BPv7 bundle with a zero-length payload block. The `canonicalizePayloadBlock()` function in `bpsec_util.c` forwards `bundle->payload.length` directly to `zco_clone()` without a zero-value guard; when that value is zero, the CHKZERO assertion fails, `sm_Abort()` is invoked, and the process terminates via SIGABRT. Critically, the crash occurs before any HMAC verification, so no credential, key, or prior session state is needed to trigger it.
Persistent denial-of-service in MongoDB Server allows any authenticated user with write privileges to trigger a fatal assertion crash via specially crafted retryable write commands, with the crash state durably written to disk so it survives server restarts. Affected releases span MongoDB 7.0.x through 7.0.40, 8.0.x through 8.0.29, and 8.3.x through 8.3.8; in sharded clusters the corrupted state can propagate across shard nodes, requiring manual DBA intervention to restore service. No public exploit has been identified and the vulnerability is not in CISA KEV, but the persistent, cluster-wide availability impact significantly elevates real-world risk beyond a transient service crash.
Persistent denial-of-service in MongoDB Server (versions 7.0.x, 8.0.x, and 8.3.x) allows an authenticated user with collection creation privileges to corrupt durable storage metadata by supplying invalid storage configuration options that bypass validation in the storage engine integration layer. The malformed values are written to disk and trigger a fatal CWE-617 assertion failure when subsequent diagnostic operations attempt to read them back, crashing the server process. Because the corrupted metadata survives server restarts and is replicated to all replica set members via the oplog, a single attack can produce a cluster-wide outage requiring manual DBA intervention at the filesystem level on every affected node. No public exploit code or CISA KEV listing exists at time of analysis.
Denial of service in MongoDB Server allows an unauthenticated remote attacker to terminate the mongod process by triggering a reachable assertion (CWE-617) in the read concern processing path. The flaw affects specific replica set member configurations across three MongoDB major release lines - 7.0.x, 8.0.x, and 8.3.x - and requires no credentials to exploit over the network. No public exploit code or active exploitation (CISA KEV) has been identified, but the zero-authentication, low-complexity network attack path makes this a meaningful availability risk for any organization running affected replica set deployments.
MongoDB Server's $regexFindAll aggregation expression contains a reachable assertion (CWE-617) that any authenticated user with aggregation pipeline execution rights can trigger to crash the mongod process. When a regex match operation begins at a byte offset falling inside a multi-code-unit character - such as a multi-byte UTF-8 sequence or a Unicode surrogate pair - the internal invariant check fires and the database process terminates, causing a full denial of service for all connected clients. No public exploit code and no CISA KEV listing exist at time of analysis, but the triggering condition is deterministic and reproducible by any authenticated attacker who can submit crafted aggregation input.
Process-terminating denial of service in libmongocrypt's decryption path allows a low-privileged attacker to crash applications using MongoDB Client-Side Field Level Encryption (CSFLE). Tracked as MONGOCRYPT-971, the vulnerability is triggered when an unexpected-size encrypted value reaches the decryption routine, firing a reachable assertion (CWE-617) that abruptly terminates the host process rather than returning a handled error. An attacker who can store crafted encrypted values in a shared MongoDB collection, or influence the encrypted data an application receives, can repeatably crash the targeted application.
Unauthenticated remote denial of service in Libreswan's pluto IKE daemon allows any network attacker to repeatedly crash and restart the VPN service by sending a malformed X.509 certificate in a CERT payload during IKE handshake negotiation. The crash is triggered by a reachable assertion in `add_decoded_cert()`: when NSS's `CERT_ExtractPublicKey()` receives a certificate with an invalid RSA exponent (e.g., zero), it returns NULL, which the FIPS-mode code path does not handle, causing the daemon to abort. The vendor explicitly confirms no remote code execution is possible; impact is limited to availability. No CISA KEV listing and no public exploit code have been identified at time of analysis.
Reachable assertion in llama.cpp's GGUF file parser (gguf_reader::read) allows a remote unauthenticated attacker to crash the process by supplying a crafted GGUF model file to any service built on llama.cpp b5693 or earlier. CWE-617 (Reachable Assertion) causes process abort on assertion failure, making this effectively a denial-of-service primitive. No public exploit code or active exploitation has been identified at time of analysis; EPSS sits at the 4th percentile (0.14%), reflecting low observed exploitation pressure.
Denial of Service in Open5GS v2.7.6 targets the NUDM-UECM (Network Unified Data Management - UE Context Management) interface, where a crafted HTTP DELETE request triggers a reachable assertion failure that crashes the UDM process. The CVSS vector (AV:N/AC:L/PR:N/UI:N) and SSVC 'Automatable: yes' rating indicate this is trivially scriptable over the network. No active exploitation or public proof-of-concept code has been identified at time of analysis.
Reachable assertion in Open5GS v2.7.6 SMF crashes the Session Management Function via a crafted DELETE request to the /nsmf-pdusession/v1/sm-contexts endpoint, enabling unauthenticated remote denial of service against the 5G core. Per CVSS PR:N, no authentication is required, though network access to the internal Service Based Interface (SBI) is a practical prerequisite in standard deployments. No active exploitation has been confirmed (not in CISA KEV), no public exploit code is known, and SSVC rates this as non-automatable with partial technical impact - suggesting real-world risk is lower than the 7.5 CVSS score implies.
