CVE-2026-19292
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
Re-pairing with a legitimate device can use a lower security level than previous making brute-forcing the LTK easier. See V4 in the BLERP paper linked below.
Risk Assessment
Lowering the security level during re-pairing increases susceptibility to brute-force attacks on the LTK, potentially leading to Bluetooth session hijacking and confidentiality breaches.
Recommendation
Update Bluetooth device firmware to enforce the highest security level during re-pairing. Also consider requiring re-authentication when changing security levels.
