jxl-oxide: integer subtraction overflow panic in cluster_from_table via crafted JXL input (DoS)

GHSA-2v8p-fqpx-2q3w

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (jxl-modular 0.11.3), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary Logic bug in decodesimpletableslow may cause integer arithmetic overflow when decoding Modular image with certain kind of MA tree, which may panic with overflow-checks enabled. Impact Denial of service: any application passing untrusted JXL data to JxlImage::renderframe (or equivalent) can be crashed. Affects all builds with overflow checks enabled, which includes debug builds and any release build that sets overflow-checks = true in Cargo.toml or [profile.]. No memory corruption is possible — the panic fires before any unsafe code is reached.

# Patch Next advisory brief: GHSA-2v8p-fqpx-2q3w

Advisory: jxl-oxide: integer subtraction overflow panic in cluster_from_table via crafted JXL input (DoS)
IDs: GHSA-2v8p-fqpx-2q3w
Record: https://patchnext.com/advisories/ghsa-2v8p-fqpx-2q3w (revision 1, source checked 26 Oct 2026, 15:42 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: jxl-modular 0.11.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- crates.io jxl-modular: affected <= 0.11.2; fixed in 0.11.3

## Suggested inspection (read-only)
- crates.io jxl-modular: 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 jxl-modular.
- 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-2v8p-fqpx-2q3w (GitHub-reviewed advisory GHSA-2v8p-fqpx-2q3w lists affected ranges: crates.io jxl-modular >=0 <=0.11.2)
