From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: balakrishna Date: Wed, 24 May 2023 13:28:21 +0530 Subject: [PATCH] Fix OOB Write in pin_reply in bluetooth.cc Root cause: if the length of "pin_code" is greater than 16, an OOBW will be triggered due to a missing bounds check. Fix: Check is added to avoid Out of Bound Write.
