CVE-2026-68319: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: pds_core: fix deadlock between reset thread and remove pci_reset_function() acquires device_lock before performing the reset. pdsc_remove() is called by the PCI core with device_lock already held. If pdsc_pci_reset_thread() is running when pdsc_remove() is called, destroy_workqueue() will block waiting for the work to complete, while the work is blocked waiting for device_lock - deadlock. Use pci_try_reset_function() which uses pci_dev_trylock() internally. This acquires both the device lock and the PCI config access lock without blocking - if either lock is contended, it returns -EAGAIN immediately. This avoids the deadlock while also ensuring proper config space access serialization during the reset. The pci_dev_get/put calls are also removed as they were unnecessary - the driver-owned workqueue is destroyed in pdsc_remove(), guaranteeing the work completes before remove returns. The PCI core holds its reference to pci_dev throughout the entire unbind sequence.
