CVE-2026-45816: CWE-476 NULL Pointer Dereference in Apache Software Foundation Apache NimBLE
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.
AI Analysis
Technical Summary
This vulnerability in Apache NimBLE (up to version 1.9.0) involves a NULL Pointer Dereference in the LE Long Term Key Request event. The flaw requires that asserts be disabled (otherwise an assert would trigger before the NULL dereference) and that the Bluetooth controller behaves incorrectly or maliciously. Due to these conditions, the severity is considered low. The Apache Software Foundation has addressed this issue in Apache NimBLE version 1.10.0.
Potential Impact
The impact is limited due to the requirement of disabled asserts and a misbehaving or bogus controller. This reduces the likelihood and severity of exploitation, making the vulnerability low risk. No known exploits are reported in the wild.
Mitigation Recommendations
Users should upgrade Apache NimBLE to version 1.10.0 or later, where this NULL Pointer Dereference vulnerability is fixed. No other mitigation steps are indicated.
