Description OSIDB Bzimport 2026-10-23 12:18:40 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: thunderx: fix PTP device ref leak in nicvf_probe()

cavium_ptp_get() acquires a reference to the PTP PCI device
through pci_get_device(). If any initialization step fails
after cavium_ptp_get(), the PTP PCI device reference is leaked.
Add a common error path to release the PTP reference before
returning from probe failures.
