The vulnerability of the s3fwrn82_uart_read() function in the drivers/nfc/s3fwrn5/uart.c file of the Linux operating system’s NFC driver module allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the s3fwrn82uartread function in the drivers/nfc/s3fwrn5/uart.c file of the Linux NFC driver module is related to the copying of buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability could allow an attacker to...
