CVE-2025-69278: 
NixOS vulnerability analysis and mitigation

CVE-2025-69278 is an improper input validation vulnerability in the NR (New Radio/5G) modem component affecting Android devices powered by Unisoc chipsets (T7300, T8100, T9100, T8200, T8300). The flaw can cause a system crash, leading to remote denial of service with no privileges required. It affects Android versions 13.0, 14.0, 15.0, and 16.0. The vulnerability was published on March 9, 2026, and carries a CVSS v3.1 base score of 7.5 (High) (Unisoc Advisory, Android Bulletin).

The vulnerability is classified as CWE-20 (Improper Input Validation) and resides in the NR modem firmware component used in Unisoc chipsets. An unauthenticated remote attacker can send specially crafted network input to the modem, triggering an unhandled condition that causes the modem — and potentially the broader device — to crash. No user interaction or elevated privileges are required, and the attack vector is entirely network-based, making it exploitable over cellular (5G NR) radio channels (Unisoc Advisory, Android Bulletin).

Successful exploitation results in a system crash of the affected Android device, causing a denial of service condition. There is no impact on confidentiality or integrity — the sole consequence is loss of availability. Devices using Unisoc T7300, T8100, T9100, T8200, or T8300 chipsets running Android 13 through 16 are at risk of being remotely crashed without any user interaction, which could disrupt communications and device functionality (Unisoc Advisory, Android Bulletin).

There is no public proof-of-concept exploit available, and no evidence of active in-the-wild exploitation has been observed as of the time of reporting. The EPSS score is approximately 0.20%, indicating a low probability of exploitation in the near term. The vulnerability has not been added to the CISA Known Exploited Vulnerabilities (KEV) catalog. No specific threat actor attribution has been made (Unisoc Advisory, Android Bulletin).

Patches have been released by both Unisoc and Google. Users should apply the Android security update dated 2026-03-01 (patch level 2026-03-01 or 2026-03-02), which addresses this vulnerability for Android 13, 14, 15, and 16. Device manufacturers using affected Unisoc chipsets should integrate the vendor-supplied fix referenced in the Unisoc support announcement. No configuration-based workaround is publicly documented; updating to the patched security patch level is the recommended remediation (Unisoc Advisory, Android Bulletin).
