Description

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_qca: fix NULL pointer dereference in qca_dmp_hdr() for non-serdev device hu->serdev is NULL for hci_uart attached via non-serdev paths, but qca_dmp_hdr() unconditionally dereferences hu->serdev->dev.driver->name, causing a NULL pointer dereference. Fix by guarding the dereference with a NULL check and falling back to "hci_ldisc_qca" for the non-serdev case.
