Upgrade espressif/esp-idf to version 5.5.2 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the bta_dm_sdp_result function. An attacker can cause memory corruption or execute arbitrary code by sending more than 32 services during the SDP process, leading to writes outside the bounds of the fixed-size uuid_list array.
Note: The maintainers are also planning to include the fix in earlier versions, including 5.4.4, 5.3.5, 5.2.7, and 5.1.7; however, at the time of writing, those versions have not yet been released.
