CVE-2026-98633
En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:
Bluetooth: btnxpuart: Fix skb leak in nxp_process_fw_dump()
Cuando CONFIG_DEV_COREDUMP=n, hci_devcd_append() devuelve -EOPNOTSUPP sin liberar su argumento skb. Esto provoca una fuga del skb clonado y, además, impide que se llame a nxp_set_ind_reset() para llevar a cabo la recuperación.
Se corrige protegiendo la llamada hci_devcd_append(hdev, skb_clone(skb, GFP_ATOMIC)) con IS_ENABLED(CONFIG_DEV_COREDUMP).
