CVE-2026-23330
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
nfc: nci: complete pending data exchange on device close
In nci_close_device(), complete any pending data exchange before closing. The data exchange callback (e.g. rawsock_data_exchange_complete) holds a socket reference.
NIPA occasionally hits this leak:
