High CVSS 8.8
CVE-2026-19293
NVD analysis in progress
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.
What this means
- Exposure
- Exploitable from the adjacent network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
