CVE-2021-22494

Status: ModifiedMedium (5.5)—

An issue was discovered in the fingerprint scanner on Samsung Note20 mobile devices with Q(10.0) software. When a screen protector is used, the required image compensation is not present. Consequently, inversion can occur during fingerprint enrollment, and a high False Recognition Rate (FRR) can occur. The Samsung ID is SVE-2020-19216 (January 2021).

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
