Description

In wlan STA FW, there is a possible out of bounds write due to improper input validation. This could lead to remote (proximal/adjacent) code execution with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00389045 / ALPS09136494; Issue ID: MSV-1796.

Security Summary

CVE-2024-20148 is an out-of-bounds write vulnerability in the WLAN Station (STA) firmware due to improper input validation, tracked under CWE-787. It affects the WLAN STA firmware component, as detailed in MediaTek's product security bulletin. The issue carries a CVSS v3.1 base score of 9.8 (Critical), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating high confidentiality, integrity, and availability impacts.

The vulnerability enables remote proximal or adjacent code execution without requiring additional privileges or user interaction. Attackers in network proximity can exploit it over the air via crafted wireless packets, potentially compromising the affected device at the firmware level.
