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 at fs/proc/generic.c:719 remove_proc_entry +0x190/0x19c
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().
