CVE-2026-19293
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
SMP security request (from peripheral) does not include the maximum encryption key size supported. Using a key with less than the maximum keysize makes brute-forcing the key easier. See V6 in BLERP paper linked below.
Risk Assessment
Using a weaker encryption key increases the risk of Bluetooth communication interception and decryption, potentially leading to data confidentiality breaches.
Recommendation
Update Bluetooth device firmware to a version that enforces the maximum encryption key size. Additionally, consider restricting the ability to negotiate lower security levels.
