An authorized user may crash the MongoDB server by causing buffer over-read. This can be done by issuing a DDL operation while queries are being issued, under some conditions. This issue affects MongoDB Server v7.0 versions prior to 7.0.25, MongoDB Server v8.0 versions prior to 8.0.15, and MongoDB Server version 8.2.0.

MongoDB Server may experience an invariant failure during batched delete operations when handling documents. The issue arises when the server mistakenly assumes the presence of multiple documents in a batch based solely on document size exceeding BSONObjMaxSize. This issue affects MongoDB Server v7.0 versions prior to 7.0.26, MongoDB Server v8.0 versions prior to 8.0.13, and MongoDB Server v8.1 versions prior to 8.1.2

An authenticated user may trigger an invariant assertion during command dispatch due to incorrect validation on the $external database. This may result in mongod denial of service or server crash. This issue affects: MongoDB Inc. MongoDB Server v5.0 versions, prior to and including v5.0.6.

An authorized user may trigger an invariant which may result in denial of service or server exit if a relevant aggregation request is sent to a shard. Usually, the requests are sent via mongos and special privileges are required in order to know the address of the shards and to log in to the shards of an auth enabled environment. This issue affects MongoDB Server v5.0 versions prior to and including 5.0.2.

An authorized user may trigger a server crash by running a $geoNear pipeline with certain invalid index hints.

An unauthenticated user can trigger a fatal assertion in the server while generating ftdc diagnostic metrics due to attempting to build a BSON object that exceeds certain memory sizes. This issue affects MongoDB Server v5.0 versions prior to and including 5.0.16 and MongoDB Server v6.0 versions prior to and including 6.0.5.

In Modem, there is a possible system crash due to improper input validation. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01717526; Issue ID: MSV-5591.

A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. If an attacker can obtain a krbtgt ticket using an older encryption type (single-DES, triple-DES, or RC4), the attacker can crash the KDC by making an S4U2Self request.
