CVE-2026-106432

A heap buffer overflow exists in the MongoDB PHP Driver due to the BSON encoder converting string lengths to 32-bit values without validation. When an application encodes a string near 4 GiB , the allocation size can wrap while the copy operation uses the original length, potentially corrupting p...

CVE-2026-106432 Heap buffer overflow via 32-bit string-length truncation in MongoDB PHP Driver

The BSON encoder in the MongoDB PHP Driver converts a string length to a 32-bit value without validation. When an affected application encodes a string near 4 GiB, the allocation size can wrap while the copy operation uses the original length. The resulting heap buffer overflow can corrupt proces...

CVE-2026-106437

The MongoDB C Driver contains an out-of-bounds read and write vulnerability within its BSON buffer-reservation API. The root cause is an integer underflow (CWE-191) that occurs when the API records a length smaller than the five-byte BSON minimum. Subsequent append or comparison operations can tr...

CVE-2026-106437 Out-of-bounds read and write via undersized BSON buffer reservation in MongoDB C Driver

The BSON buffer-reservation API in the MongoDB C Driver can record a length smaller than the five-byte BSON minimum. Later append or comparison operations can underflow unsigned length calculations and read or write outside the document buffer. An actor who can influence the length supplied by an...
