In the Linux kernel, the following vulnerability has been resolved:
firewire: ohci: prevent leak of left-over IRQ on unbind
Commit 5a95f1ded28691e6 ("firewire: ohci: use devres for requested IRQ")
also removed the call to free_irq() in pci_remove(), leading to a
leftover irq of devm_request_irq() at pci_disable_msi() in pci_remove()
when unbinding the driver from the device
remove_proc_entry: removing non-empty directory 'irq/136', leaking at
least 'firewire_ohci'

remove irq with devm_free_irq() before pci_disable_msi()
also remove it in fail_msi: of pci_probe() as this would lead to
an identical leak
A vulnerability was found in the Linux kernel's FireWire OHCI driver, which could lead to a resource leak by leaving behind an interrupt request (IRQ) when a device is unbound. This issue may cause instability or improper handling of IRQs, potentially affecting system performance or reliability.
Отчет
Red Hat Enterprise Linux is not vulnerable to this CVE, as it does not affect the versions or configurations of the Linux kernel used in its distributions.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
