NULL Pointer Dereference vulnerability in Apache NimBLE in LE Long Term Key Request event. (CVE-2026-45816)
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.
AI Analysis
Technical Summary
CVE-2026-45816 is a NULL Pointer Dereference vulnerability in Apache NimBLE's handling of the LE Long Term Key Request event. The vulnerability can be triggered only if asserts are disabled and a malformed or malicious Bluetooth controller sends a crafted event. This reduces the likelihood and impact of exploitation. The flaw affects all Apache NimBLE versions before 1.10.0, and upgrading to 1.10.0 mitigates the vulnerability.
Potential Impact
The vulnerability can cause a denial of service (application crash) due to NULL pointer dereference, impacting availability. There is no impact on confidentiality or integrity. Exploitation requires specific conditions (disabled asserts and a malicious controller), limiting the risk.
Mitigation Recommendations
Upgrade Apache NimBLE to version 1.10.0 or later, where this vulnerability is fixed. No other mitigations are indicated or required.
