CVE-2024-47250 | Apache NimBLE: Lack of input validation in HCI advertising report could lead to potential out-of-bound access

Out-of-bounds Read vulnerability in Apache NimBLE. Missing proper validation of HCI advertising report could lead to out-of-bound access when parsing HCI event and thus bogus GAP 'device found' events being sent. This issue requires broken or bogus Bluetooth controller and thus severity is considered low. This issue affects Apache NimBLE: through 1.7.0. Users are recommended to upgrade to version 1.8.0, which fixes the issue.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
5.0 3.1 MEDIUM
CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L Click to expand
Attack vector (AV:A)
Attacker has to be nearby on the network—same office, same link, that vibe—not the whole wide internet.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
