Low risk8th percentile - higher than 8% of all known CVEs
Summary
A stack-based buffer overflow vulnerability exists in the mtk_dut binary of Linksys E7350 routers (Firmware 1.1.00.032). The function sub_4045A8 reads up to 256 bytes from /sys/class/net/%s/address into a local buffer and copies it into caller-provided buffer a1 using strcpy without boundary checks. Since a1 is often allocated with significantly smaller sizes (20-32 bytes), local attackers controlling the contents of /sys/class/net/%s/address can trigger buffer overflows.
Risk Assessment
The risk includes memory corruption, denial of service (DoS), and potential arbitrary code execution by a local attacker, which could lead to device compromise.
Recommendation
Immediately update the Linksys E7350 router firmware to the latest version that fixes this vulnerability. If no update is available, restrict local access to the device.
