Linux Kernel Resource Leak Vulnerability in tty Component

A vulnerability in the Linux kernel's tty component could lead to a resource leak during the 'icom_probe' process. This issue arises when 'pci_read_config_dword' fails, as the allocated resources are not properly released. The vulnerability has been addressed by modifying the probe function to call 'pci_release_regions' and 'pci_disable_device' in such failure scenarios, ensuring that resources are recycled appropriately.

Impact

Exploitation of this vulnerability could result in a resource leak, potentially leading to degraded system performance or stability.
