In the Linux kernel, the following vulnerability has been resolved: nfc: nci: Fix uninit-value in nci_rx_work syzbot reported the following uninit-value access issue [1] nci_rx_work() parses received packet from ndev->rx_q. It should be validated header size, payload size and total packet size before processing the packet. If an invalid packet is detected, it should be silently discarded.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nfc: nci: corrigió el valor uninit en nci_rx_work syzbot informó el siguiente problema de acceso al valor uninit [1] nci_rx_work() analiza el paquete recibido de ndev->rx_q.
