CVE-2026-20463
MediumCVSS 6.7Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
In the Modem module, a vulnerability was found that allows privilege escalation through a permissions bypass. This can be exploited locally if the attacker already has System privileges. User interaction is not required for exploitation.
Risk Assessment
The risk involves an attacker with existing System privileges being able to gain higher privileges, potentially leading to full device compromise.
Recommendation
It is recommended to immediately apply patch MOLY01716533 provided by the vendor. Update the modem software to the latest version.
Other vulnerabilities in Modem
See all- CVE-2026-66085Medium
In modem, there is a possible information disclosure due to missing filtering of sensitive data in crash dumps. This could lead to local information disclosure with no additional execution privileges needed.
- CVE-2026-20543Medium
In the Modem component, there is a possible information disclosure due to a logic error. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
- CVE-2026-20541Medium
In the Modem component, there is a possible out-of-bounds read due to a missing permission check. This could lead to remote denial of service 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.
- CVE-2026-20540Medium
In the Modem component, 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 has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation.
- CVE-2026-20539Medium
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.
- CVE-2026-20538Medium
In the Modem module, there is a possible out-of-bounds read due to a missing permission 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.
- CVE-2026-20534Medium
In the Modem module, there is a possible out-of-bounds read due to an incorrect 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.
- CVE-2026-20527Medium
In the Modem component, there is a possible system crash 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. No additional execution privileges or user interaction are needed.
- 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.
Original NVD description (English source)
In Modem, there is a possible escalation of privilege due to a permissions bypass. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: MOLY01716533; Issue ID: MSV-6309.
