CVE-2025-20739
MediumCVSS 6.7Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
In the wlan AP driver, there is a possible out-of-bounds write due to an incorrect bounds check. This could lead to local privilege escalation if a malicious actor has already obtained System privileges. No user interaction is required for exploitation.
Risk Assessment
A local attacker with System privileges could exploit this vulnerability to escalate privileges and take control of the device. However, prior high privileges are required.
Recommendation
Update the wlan AP driver to the version containing patch WCNCR00435340. Restrict access to devices using this driver to trusted networks and users.
