Apache NimBLE versions prior to 1.10.0 have a buffer size miscalculation vulnerability when processing Legacy Advertising Report HCI events that include multiple reports. This flaw causes the host to read beyond the buffer boundary, resulting in corrupted GAP events delivered to the application. The vulnerability is considered low severity in typical use because NimBLE's own controller does not batch multiple reports, so the issue only arises when used with third-party controllers that do. The vulnerability is fixed in version 1.10.0.

A buffer overflow vulnerability exists in Apache NimBLE through version 1.9.0 due to improper size checking when copying received HCI events into the event pool. Exploitation requires a misconfigured event pool size or a malicious/compromised controller on the HCI socket link, and cannot be triggered via over-the-air Bluetooth access. The vulnerability is fixed in version 1.10.0.

A NULL Pointer Dereference vulnerability exists in Apache NimBLE affecting the LE Long Term Key Request event. This issue requires disabled asserts and a misbehaving or bogus controller to trigger, which reduces its practical severity. The vulnerability affects Apache NimBLE versions prior to 1.10.0. Upgrading to version 1.10.0 resolves the issue.

An improper input validation vulnerability exists in Apache NimBLE through version 1.9.0 in the Mesh Proxy SAR reassembly component. This flaw can cause broken data to be passed to the application, resulting in memory pressure and unstable parsing behavior. The issue is fixed in version 1.10.0.

Improper Input Validation vulnerability in Apache NimBLE in Mesh Proxy SAR reassembly could result in passing broken data toward application resulting in memory pressure and unstable parsing behavior. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.

NULL Pointer Dereference vulnerability in Apache NimBLE in LE Long Term Key Request event. This requires disabled asserts (otherwise assert would trigger before NULL dereference) and bogus (or misbehaving) controller, thus severity is low. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.

Reachable Assertion vulnerability in Apache NimBLE. A specially crafted ATT Read Multiple Variable Response (BLE_ATT_OP_READ_MULT_VAR_RSP) may trigger assert in ATT parser. Severity is medium as this requires DUT to first send ATT Read Multiple Variable Request. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.

Out-of-bounds Write, Integer Underflow (Wrap or Wraparound) vulnerability in Apache NimBLE BASS service. Improper validation when parsing BASS service  "Add Source" and "Modify Source" operation PDU could results in stack buffer overflow or arbitrary out-of-bound read. This can be triggered by nearby devices over Bluetooth connection, however pairing is required prior to accessing BASS service, which depending on device configuration may or may not require user action. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.

Incorrect Calculation of Buffer Size vulnerability in Apache NimBLE when processing Legacy Advertising Report HCI event. When a single HCI advertising report event bundles multiple reports, NimBLE miscalculated the offset to the next report. This can cause the host to read past the end of the buffer and deliver a GAP event with bogus data to the application. Severity is low: NimBLE's own controller never batches multiple reports into one event, so this only matters when NimBLE's host is paired with a third-party controller that does. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Apache NimBLE. The HCI socket transport did not check whether a received HCI event would fit the configured event pool before copying it, allowing a buffer overflow. Severity is low: exploitation requires either a misconfigured pool size or a malicious/compromised controller on the other end of the HCI socket link, not over-the-air Bluetooth access. This issue affects Apache NimBLE: through 1.9.0. Users are recommended to upgrade to version 1.10.0, which fixes the issue.
