nfc: nci: assert requested protocol is valid
stable inclusion from stable-v5.10.199 commit a424807d860ba816aaafc3064b46b456361c0802 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95B1K CVE: CVE-2023-52507 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=a424807d860ba816aaafc3064b46b456361c0802 --------------------------- [ Upstream commit 354a6e70 ] The protocol is used in a bit mask to determine if the protocol is supported. Assert the provided protocol is less than the maximum defined so it doesn't potentially perform a shift-out-of-bounds and provide a clearer error for undefined protocols vs unsupported ones.
