In the Linux kernel, the following vulnerability has been resolved: misc: pci_endpoint_test: Avoid issue of interrupts remaining after request_irq error After devm_request_irq() fails with error in pci_endpoint_test_request_irq(), the pci_endpoint_test_free_irq_vectors() is called assuming that all IRQs have been released. However, some requested IRQs remain unreleased, so there are still /proc/irq/* entries remaining, and this results in WARN() with the following message: remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'pci-endpoint-test.0' WARNING: CPU: 0 PID: 202

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2025-23140 is a none public vulnerability record for Linux Linux. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether Linux Linux is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: Linux Linux e03327122e2c8e6ae4565ef5b3d3cbe4364546a1 <0557e70e2aeba8647bf5a950820b67cfb86533db (e03327122e2c8e6ae4565ef5b3d3cbe4364546a1 <0557e70e2aeba8647bf5a950820b67cfb86533db). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.

Security analyst

Signals on file: CVSS 0.0, EPSS 22.0%. It is not currently listed in the CISA Known Exploited catalog. Sources contributing to this record: cve_org, euvd. Public exploit references, when present, are outbound links only and are not proof of active exploitation. This is a catalog interpretation of stored metadata.
