MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk8th percentile - higher than 8% of all known CVEs
Summary
A vulnerability in the Modem component allows remote denial of service due to improper input validation. An attacker can cause a system crash by luring a UE to connect to a rogue base station.
Risk Assessment
The risk involves potential remote disruption of network services for users connected to a malicious base station, leading to communication outages and loss of availability.
Recommendation
Apply the vendor patch MOLY01826924 immediately and implement base station authentication mechanisms to mitigate the risk.
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.
