CVE-2025-23140
Estado: AnalizadaMedia (5.5)—
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:
To solve this issue, set the number of remaining IRQs to test->num_irqs, and release IRQs in advance by calling pci_endpoint_test_release_irq().
