Why now
MongoDB 5.0 and later need AVX
On x86_64, MongoDB 5.0 and later require the AVX instruction set. Older hardware and some hypervisor CPU models, such as the generic kvm64 profile, do not expose AVX, so mongod typically crashes on start with an illegal instruction error. Estates on that hardware are held on 4.4 until the platform changes.
Upgrades go one major version at a time
MongoDB requires each major version to be installed in turn, with featureCompatibilityVersion raised at every step. Moving from 4.4 to 7.0 means three full upgrades of every replica set and sharded cluster, each with its own driver compatibility checks.
Post-EOL fixes are discretionary
MongoDB's support policy carries no obligation to support versions past end of life. It has shipped some post-EOL releases, such as the December 2025 fixes for CVE-2025-14847, but 4.2 and earlier received no fix for that known-exploited flaw at all. Estates that need a commitment, not a hope, need someone contracted to deliver it.

How it installs
OSSeva artifacts arrive via your existing package infrastructure. Pull the patched version the same way you pull upstream today — just from the OSSeva registry.
# MongoDB 5.0+ on x86_64 needs AVX. Empty output means this host cannot run it.

MongoDB's commercial support covers its supported releases. For self-managed Community Server estates held on end-of-life versions by hardware, drivers or certification, OSSeva patches the version you run while the upgrade is planned.

Frequently asked questions
Why does MongoDB 5.0 fail with an illegal instruction error?
MongoDB 5.0 and later require the AVX instruction set on x86_64. If the CPU, or the CPU model exposed by the hypervisor, does not provide AVX, mongod crashes on start. The official Docker image prints a warning that MongoDB 5.0+ requires a CPU with AVX support. Run it on AVX-capable hardware, expose AVX from the hypervisor, or stay on 4.4 with extended support.
Can I upgrade MongoDB 4.4 directly to 7.0?
No. MongoDB upgrades go through each major release in turn: 4.4 to 5.0, 5.0 to 6.0, then 6.0 to 7.0, raising featureCompatibilityVersion after each step.
Does OSSeva support MongoDB Atlas?
No. Atlas is MongoDB's managed service and MongoDB patches it. OSSeva supports self-managed MongoDB Community Server.
How is licensing handled?
MongoDB Community Server is distributed under the Server Side Public License. OSSeva provides patched builds and support for your own self-managed use; running MongoDB as a service for third parties has separate SSPL obligations that apply whoever supports it.
