Last modified
CVE-2020-13594 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.2 and earlier (for ESP32 devices) does not properly restrict the channel map field of the connection request packet on reception, allowing attackers in radio range to cause a denial of service (crash) via a crafted packet.. EPSS estimates a 0.76% chance of exploitation in the next 30 days.
