Name: ASA-2024-010: Mismatched bit-length in sdk.Int and sdk.Dec can lead to panic Component: Cosmos SDK / Math Criticality: High (Considerable Impact, and Possible Likelihood per ACMv1.2) Affected versions: cosmossdk.io/math package versions <= math/v1.3.0 Affected users: Chain Builders + Maintainers, Validators Impact The bit-length in sdk.Int and sdk.Dec are not aligned, which may present a possible panic condition when interacting with Dec types in an Int context. This issue was resolved by aligning the max size between the data types in the cosmossdk.io/math package. This issue impacts consumers of the cosmossdk.io/math, which includes popular modules including IBC-Go and tokenfactory (permissionless). If your chain interacts with APIs in the cosmossdk.io/math package, or utilizes a module that consumes this library, it is advised to update to the latest version at the time of the patch release by updating your project's go.mod dependency for cosmossdk.io/math. The patch can be…

# Patch Next advisory brief: GHSA-7225-m954-23v7

Advisory: ASA-2024-010: cosmossdk.io/math: Mismatched bit-length validation in sdk.Int and sdk.Dec can lead to panic
IDs: GHSA-7225-m954-23v7
Record: https://patchnext.com/advisories/ghsa-7225-m954-23v7 (revision 1, source checked 26 Oct 2026, 15:08 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: cosmossdk.io/math 1.4.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go cosmossdk.io/math: affected <= 1.3.0; fixed in 1.4.0

## Suggested inspection (read-only)
- Go cosmossdk.io/math: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on cosmossdk.io/math.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-7225-m954-23v7 (GitHub-reviewed advisory GHSA-7225-m954-23v7 lists affected ranges: Go cosmossdk.io/math >=0 <=1.3.0)
