Denial of service in MongoDB's aggregation framework allows an authenticated database user with write access to crash the mongod process by triggering a specific data type conversion operation that consumes disproportionate memory, causing the operating system's out-of-memory killer to terminate the process under memory pressure. Affected are MongoDB server deployments where low-privileged users can run aggregation queries; the CVSS 4.0 score is 7.1 with high availability impact and no confidentiality or integrity impact. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in MongoDB Server (mongod) allows an authenticated user with aggregation privileges to force the operating system to terminate the mongod process under memory pressure by abusing the $rankFusion and $scoreFusion hybrid-search aggregation stages. The flaw sits in the server's error-handling path and requires only the ability to run aggregation queries, causing an OOM-triggered crash of the database instance. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in MongoDB's mongod server allows any authenticated user holding only read privileges to crash the database by submitting aggregation pipeline expressions that invoke server-side JavaScript, triggering a use-after-free (CWE-416) during document processing. The flaw affects availability only and requires valid low-privilege credentials; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in MongoDB allows an authenticated attacker to exhaust server CPU by submitting query operations that use deeply nested $jsonSchema validation constructs, producing a runaway CPU-bound operation that cannot be halted via standard administrative controls such as killOp. Reported by MongoDB's own CNA (SERVER-125872) and classified as inefficient algorithmic complexity (CWE-407), with no public exploit identified at time of analysis. The inability to interrupt the operation elevates this above a routine resource-consumption bug because normal recovery tooling is ineffective.
Denial of service in MongoDB Server allows an authenticated database user to submit an aggregation/query expression that generates very large arrays, forcing the server to allocate oversized intermediate objects in memory and crash with an out-of-memory (OOM) error. Reported by MongoDB's own CNA and tracked in SERVER-124355, the flaw carries a CVSS 4.0 base score of 7.1 with an availability-only impact (VA:H). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Denial of service in MongoDB Server (mongod) lets any authenticated user with aggregation-pipeline privileges crash the database process by invoking the internal `$_internalIndexKey` aggregation expression against a compound wildcard index. The expression fails to handle compound wildcard index specifications, tripping an internal consistency check (assertion) that aborts the server. No public exploit identified at time of analysis, and the flaw is reported by MongoDB's own CNA as a Denial of Service issue with no confidentiality or integrity impact.
Out-of-bounds memory read in FFmpeg's S/PDIF muxer (spdifenc.c) affects versions 0.7.1 through 8.1.2 when re-muxing DTS-HD audio to an S/PDIF (IEC 61937) container. The spdif_header_dts4 function trusts an attacker-controlled core_size field from a crafted DTS stream without validating it against the actual packet length, letting a malicious input read memory past the packet buffer to leak small amounts of adjacent process memory or crash the process. Reported by VulnCheck with an upstream fix available; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Out-of-bounds heap read in MongoDB Server's BSON CodeWScope element accessors lets an authenticated user disclose adjacent heap memory or crash the server (denial of service) by submitting a crafted aggregation pipeline. The exploit path abuses malformed BSONColumn (columnar/compressed BSON) data whose CodeWScope element bypasses the normal wire-level BSON validation, so an unchecked size field is trusted during decompression. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the CVSS 4.0 base score is 7.1, driven mainly by high availability impact.
Denial of service in MongoDB Server (mongod) allows an authenticated user holding only basic write privileges to crash the database process by submitting a crafted transaction command that omits some required fields. The inconsistent validation of related transaction parameters trips a fatal internal invariant (CWE-617), aborting mongod and interrupting availability for all clients. No public exploit has been identified at time of analysis, and the flaw is not listed in CISA KEV; impact is limited to availability, with no data disclosure or integrity effect.
Information disclosure in MongoDB's server-side JavaScript engine allows authenticated database users to read fragments of internal server process memory. The flaw stems from improper handling of DBPointer objects during BSON serialization, causing uninitialized or adjacent memory contents to be returned to the client. Only deployments that enable server-side JavaScript are affected; no public exploit has been identified at time of analysis and it is not listed in CISA KEV.
Denial of service in MongoDB Server allows an authenticated user to exhaust CPU or trigger out-of-memory conditions by submitting a crafted Queryable Encryption 'find' payload whose unvalidated field drives an internal computation loop. The resulting resource exhaustion degrades availability for all other operations on the affected instance. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the issue is tracked internally as MongoDB SERVER-127566.
Integrity corruption in MongoDB's Queryable Encryption on sharded clusters lets an authenticated user with write access to a QE-enabled collection tamper with server-controlled encryption metadata by routing crafted write commands through the mongos router, breaking the correctness of encrypted queries. The CVSS 4.0 vector (VI:H, VC:N, VA:N) confirms this is an integrity-only issue despite the input's 'Information Disclosure' tag, which appears mislabeled. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Local privilege escalation in PortProtonQt (the Qt-based front-end for the PortProton Linux gaming launcher) before commit 0d0f0950 lets any unprivileged local user gain root-equivalent control over storage and networking. The shipped Polkit rule authorized privileged udisks2 and NetworkManager actions by inspecting the caller's process command line via `ps` for the string "ppqtos", a check any user can trivially spoof to bypass authorization. There is no public exploit code and it is not in CISA KEV, but the vulnerable rule and its trivial bypass are fully disclosed in the advisory and patch, and the vendor has released a fix (version 1.3.1).
