CVE-2022-50005 nfc: pn533: Fix use-after-free bugs caused by pn532_cmd_timeout

In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: Fix use-after-free bugs caused by pn532cmdtimeout When the pn532 uart device is detaching, the pn532uartremove is called. But there are no functions in pn532uartremove that could delete the cmdtimeout timer, which wil...

CVE-2022-50005

The CVE-2022-50005 issue concerns Linux kernel NFC code for pn533 devices. The root cause is a use-after-free caused by a timer (cmd_timeout) not being canceled during pn532_uart_remove(), allowing a concurrent use path to dereference freed memory. The fix adds del_timer_sync() in pn532_uart_remo...
