CVE-2026-20479
HighCVSS 7.5Exploitation Probability (EPSS)
Low risk41th percentile - higher than 41% of all known CVEs
Summary
In Modem, a missing bounds check could lead to an out-of-bounds read, allowing remote denial of service if the UE connects to a rogue base station controlled by the attacker. No additional privileges or user interaction are needed.
Risk Assessment
An attacker with a rogue base station could disrupt modem operation, causing loss of network connectivity.
Recommendation
Apply patch MOLY00741071 which adds bounds checking.
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.
