CI tests fail under Node.js 24.15.0 LTS (EBADF)

[MikeMcC399]

Current behavior

Running typecheck, lint or test, as used in .github/workflows/ci.yml, fails when run locally under Node.js 24.15.0 LTS with:

Error: EBADF: bad file descriptor, fstat

This issue can also be expected to appear soon under GitHub Actions and cause CI workflow failure if / when the cached Node.js versions in GitHub Actions runner images are updated to include Node.js 24.15.0 LTS.

Expected behavior

It should be possible to test Corepack successfully under Node.js Active LTS, including under the latest release Node.js 24.15.0.

Versions

Corepack 0.34.7
Ubuntu 24.04.4 LTS
Node.js 24.15.0 (Active LTS)
Yarn 4.11.0

Steps to reproduce

Install Node.js 24.15.0 LTS, then execute:

git clone https://github.com/nodejs/corepack
cd corepack
npm uninstall yarn -g # if previously installed
npm install corepack -g
corepack yarn install
corepack yarn build
corepack yarn typecheck
corepack yarn lint
corepack yarn test

Logs

$ corepack yarn install
corepack yarn build
corepack yarn test

The corresponding Yarn Berry issues:

• [Bug?]: Another case of EBADF. Node 24.15.0 (LTS) yarnpkg/berry#7102
• [BUG] HAS_BROKEN_FSTAT_FOR_ZIP_FDS version gate should include Node 24.15+ yarnpkg/berry#7103

state that this issue is fixed in yarn@v4.14.1

The results of attempting to fix with an upgrade are as follows:

command	Yarn 4.11.0	Yarn 4.14.1
corepack yarn typecheck	Error: EBADF	success
corepack yarn lint	Error: EBADF	TypeError
corepack yarn test	Error: EBADF	success

TypeError issue carried over to #814 for issue separation purposes.
