Echo-Mate

Use After Free vulnerability in No-Chicken Echo-Mate.This issue affects Echo-Mate: before V250329.

CVE-2026-4752 identifies a Use After Free (UAF) vulnerability classified under CWE-416 in the No-Chicken Echo-Mate product, affecting versions prior to V250329. Use After Free vulnerabilities occur when a program continues to use memory after it has been freed, potentially leading to arbitrary code execution, data corruption, or system crashes. In this case, the vulnerability requires local access with high privileges and does not require user interaction, indicating that an attacker must already have significant access to the system to exploit it. The CVSS v3.1 score of 6.4 reflects a medium severity, with the vector indicating local attack vector (AV:L), high attack complexity (AC:H), high privileges required (PR:H), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches have been released yet, and no exploits are known to be active in the wild. The vulnerability could allow an attacker to execute arbitrary code or cause denial of service by manipulating memory management within Echo-Mate. Given the requirement for high privileges and local access, exploitation is limited to insiders or attackers who have already compromised a system to some extent. The lack of user interaction needed means that once local access is gained, exploitation can be automated or triggered without further user involvement. This vulnerability highlights the importance of secure memory management in software handling privileged operations.

CVE-2026-4752: CWE-416 Use After Free in No-Chicken Echo-Mate

Use After Free vulnerability in No-Chicken Echo-Mate (‎SDK/rv1106-sdk/sysdrv/source/kernel/mm modules). This vulnerability is associated with program files rmap.C‎.

This issue affects Echo-Mate: before V250329.

CVE-2026-4737 is a Use After Free vulnerability categorized under CWE-416 affecting the No-Chicken Echo-Mate product, particularly versions prior to V250329. The flaw resides in the kernel memory management modules of the SDK, specifically within the rmap.C source file. Use After Free vulnerabilities occur when a program continues to use memory after it has been freed, potentially leading to memory corruption, arbitrary code execution, or system crashes. This vulnerability requires local access with low privileges and has a high attack complexity, meaning exploitation is non-trivial but feasible under certain conditions. The CVSS 4.0 base score is 7.3, reflecting significant impact on confidentiality, integrity, and availability, with high scope and vector complexity. No user interaction is needed, and no known exploits have been reported in the wild to date. The vulnerability affects the kernel-level components, increasing the risk of severe system compromise if exploited. The absence of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for vigilance and mitigation.

CVE-2026-4737: CWE-416 Use After Free in No-Chicken Echo-Mate

Improper Handling of Values vulnerability in No-Chicken Echo-Mate (SDK/rv1106-sdk/sysdrv/source/kernel/include/net/netfilter modules). This vulnerability is associated with program files nf_tables.H‎, nft_byteorder.C‎, nft_meta.C‎.

This issue affects Echo-Mate: before V250329.

CVE-2026-4736 is a vulnerability classified under CWE-229, indicating improper handling of values within the No-Chicken Echo-Mate product, specifically in the kernel-level netfilter modules (nf_tables.H, nft_byteorder.C, nft_meta.C). These modules are responsible for packet filtering and network traffic control. The flaw arises from incorrect validation or sanitization of input values, which can lead to unexpected behavior such as memory corruption, logic errors, or privilege escalation. The vulnerability affects Echo-Mate versions prior to V250329 and requires local attacker access with low privileges. The CVSS 4.0 score of 7.3 reflects a high severity, with attack vector local (AV:L), high attack complexity (AC:H), no privileges required (PR:L), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (all high). The vulnerability’s exploitation could allow an attacker to manipulate network filtering rules or kernel behavior, potentially leading to unauthorized data access, system compromise, or denial of service. No public exploits or patches are currently available, indicating the need for proactive mitigation and monitoring. The vulnerability is particularly critical in environments relying on Echo-Mate for network security enforcement, as exploitation could undermine network defenses.
