NULL pointer dereference vulnerability in SMP LTK request

CVE-2026-45816 [CVE] [CVE json] [OSV json]

Last updated: 2026-07-24T12:11:08.240Z

Affected

  • Apache NimBLE through 1.9.0

Description

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.

Remote reachable assertion in ATT Read Multiple Variable Response handler

CVE-2026-45815 [CVE] [CVE json] [OSV json]

Last updated: 2026-07-24T12:10:37.291Z

Affected

  • Apache NimBLE through 1.9.0

Description

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.

Incorrect data validation in BASS add/modify source operation

CVE-2026-45813 [CVE] [CVE json] [OSV json]

Last updated: 2026-07-24T12:10:10.910Z

Affected

  • Apache NimBLE through 1.9.0

Description

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.

OOB Read via sizeof(pointer) in Legacy Advertising Report Handler

CVE-2026-45812 [CVE] [CVE json] [OSV json]

Last updated: 2026-07-24T12:09:37.486Z

Affected

  • Apache NimBLE through 1.9.0

Description

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 overflow in socket HCI transport

CVE-2026-45811 [CVE] [CVE json] [OSV json]

Last updated: 2026-07-24T12:09:09.262Z

Affected

  • Apache NimBLE through 1.9.0

Description

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.
