Last modified

CVE-2026-28528 is a low-severity vulnerability rated 2.1/10 on the CVSS scale. BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Browsing Target GET_FOLDER_ITEMS handler that fails to validate packet boundaries and attribute count data. An attacker with a paired Bluetooth Classic connection can exploit insufficient bounds checking on the attr_id parameter to cause crashes and corrupt attribute bitmap state.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
