CVE-2026-106437

A flaw was found in mongo-c-driver. An attacker who can influence the buffer length supplied by an embedding application can trigger an integer underflow by passing an undersized value to the Binary JSON BSON buffer-reservation function. This issue leads to out-of-bounds memory reads and writes...

CVE-2026-106431

A flaw was found in mongo-c-driver. An off-by-one error in the BSON bulk document writer allows an attacker to cause a Denial of Service DoS or memory corruption. By supplying documents of a specific cumulative size that align with a buffer boundary, an attacker can trigger a single-byte...
