CVE-2025-53470 describes an out-of-bounds read vulnerability in the Apache NimBLE HCI H4 driver, affecting all versions through 1.8. A specially crafted HCI event could trigger an invalid memory read within the H4 driver. The severity is considered Low (CVSS 3.1: AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) due to the requirement of a broken or bogus Bluetooth controller, limiting its attack complexity and potential impact to low confidentiality. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this vulnerability. Users are advised to upgrade to Apache NimBLE version 1.9 to remediate this issue.
