CVE-2026-20539
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk7th percentile - higher than 7% of all known CVEs
Summary
In the Modem module, there is a possible out-of-bounds read due to a missing bounds check. This could lead to remote denial of service if a UE connects to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not required for exploitation.
Risk Assessment
The risk to the organization is potential remote denial of service that could disrupt devices using the modem. The attacker can exploit the vulnerability without user interaction, increasing the risk.
Recommendation
Apply patch MOLY01774038 (Issue ID: MSV-8913) to the Modem module. Also monitor cellular connections for suspicious base stations.

- CVE-2026-20526High
In the Modem component, there is a possible out-of-bounds write due to a missing bounds check. This could lead to remote privilege escalation if a UE connects to a rogue base station controlled by the attacker. User interaction is needed, but no additional execution privileges are required.
- CVE-2026-20525Medium
In the Modem component, there is a possible system crash due to improper input validation. This could lead to remote denial of service if a UE connects to a rogue base station controlled by the attacker. No additional execution privileges or user interaction are needed.
- CVE-2026-20520High
In the Modem component, there is a possible out-of-bounds write due to a missing bounds check. This could lead to remote privilege escalation if a UE connects to a rogue base station controlled by the attacker. No additional execution privileges or user interaction are needed.
- CVE-2026-20519High
In Modem, 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 has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation.
