CVE-2025-58349: n/a
CVE-2025-58349 is a vulnerability in the LTE MAC layer of various Samsung Mobile, Wearable, and Modem Exynos processors. It involves incorrect handling of LTE MAC packets containing many MAC Control Elements, which can cause baseband crashes. The issue affects a wide range of Exynos processors and modems. No patch or official remediation guidance is currently available. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability affects the LTE MAC layer implementation in multiple Samsung Exynos processors and modems, including models 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 2500, 9110, W920, W930, W1000, and modems 5123, 5300, and 5400. The flaw arises from improper handling of LTE MAC packets that contain numerous MAC Control Elements, leading to baseband crashes. The vulnerability was published in April 2026, but no CVSS score or remediation information is currently provided.
Potential Impact
The vulnerability can cause baseband crashes on affected devices when processing LTE MAC packets with many MAC Control Elements. This may result in temporary loss of cellular connectivity or device instability related to the baseband processor. There is no evidence of exploitation in the wild or further impact such as code execution or data leakage reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation has been published at this time. Users and administrators should monitor Samsung's security advisories for updates.
