"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npds_core: fix deadlock between reset thread and remove\n\npci_reset_function() acquires device_lock before performing the reset.\npdsc_remove() is called by the PCI core with device_lock already held.\nIf pdsc_pci_reset_thread() is running when pdsc_remove() is called,\ndestroy_workqueue() will block waiting for the work to complete, while\nthe work is blocked waiting for device_lock - deadlock.\n\nUse pci_try_reset_function() which uses pci_dev_trylock() internally.\nThis acquires both the device lock and the PCI config access lock\nwithout blocking - if either lock is contended, it returns -EAGAIN\nimmediately. This avoids the deadlock while also ensuring proper\nconfig space access serialization during the reset.\n\nThe pci_dev_get/put calls are also removed as they were unnecessary -\nthe driver-owned workqueue is destroyed in pdsc_remove(), guaranteeing\nthe work completes before remove returns. The PCI core holds its\nreference to pci_dev throughout the entire unbind sequence."
