CVE-2026-20432
HighCVSS 8.0Exploitation Probability (EPSS)
Low risk22th percentile - higher than 22% of all known CVEs
Summary
In the Modem component, there is a possible out-of-bounds write due to a missing bounds check. This could lead to remote escalation of privilege if a UE connects to a rogue base station controlled by the attacker. User interaction is required for exploitation.
Risk Assessment
An attacker can gain elevated privileges on the device, potentially leading to control over the modem and possibly the entire device.
Recommendation
Apply the patch identified as MOLY01406170, available from the modem manufacturer.
