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 then 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, leading to memory corruption, denial of service, or potential arbitrary code execution.
Security readout for executives and security teams
Plain-English summary
CVE-2025-60695 is a memory-safety flaw reported in Linksys E7350 router firmware 1.1.00.032. A local attacker who can influence a network-interface address value could crash the affected binary or potentially run code. The available sources do not name a vendor patch or confirm exploitation in the wild.
Executive priority
Treat this as a moderate operational risk for affected routers, not a confirmed internet-wide emergency. Prioritize asset identification and vendor-firmware review, especially where routers protect sensitive sites or are reachable by untrusted local users.
Technical view
The report describes a stack-based buffer overflow in the mtk_dut binary. Function sub_4045A8 reads up to 256 bytes from /sys/class/net/%s/address, then uses strcpy into smaller caller buffers, reportedly 20-32 bytes. The CVE is CWE-121 with CVSS 3.1 score 5.9 and local attack vector.
Likely exposure
Exposure appears limited to Linksys E7350 routers running firmware 1.1.00.032, based on the CVE description. The structured affected-product fields are incomplete, so vulnerability managers should verify inventory against exact model and firmware rather than assuming broader Linksys impact.
Exploitation context
The source bundle says KEV is false, and no cited source states active exploitation. The described attack requires local conditions and control over the relevant sysfs address content. Evidence does not support treating this as remotely exploitable from the internet.
Researcher notes
The technical report identifies a risky strcpy pattern and small destination buffers, but public affected-product metadata is incomplete and vendor remediation is not cited. Avoid extrapolating beyond Linksys E7350 firmware 1.1.00.032 unless additional vendor evidence appears.
Mitigation direction
Check Linksys support guidance for firmware updates or advisories for E7350 firmware 1.1.00.032.
Restrict administrative, shell, and local network access to affected routers.
Prioritize replacement or isolation if no vendor-supported firmware is available.
Monitor affected devices for unexpected crashes, reboots, or configuration changes.
Validation and detection
Inventory Linksys E7350 routers and record exact firmware versions.
Confirm whether firmware 1.1.00.032 is present in production.
Review Linksys guidance for any fixed firmware or workaround.
Assess who has local or administrative access to affected devices.
Track device stability signals such as unexplained mtk_dut failures or reboots.

Stack-based Buffer Overflow
Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
