Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

covesa Open1722是covesa组织的一款网络服务器设备。 covesa Open1722 0.9.2及之前版本存在缓冲区错误漏洞，该漏洞源于avtp_to_can()函数在写入时未对调用方提供的数组大小进行边界检查，导致栈缓冲区溢出，可能允许未经身份验证的远程攻击者通过发送包含超过15个ACF-CAN消息的特制UDP数据报破坏相邻栈内存，从而执行任意代码或造成拒绝服务。

Vulnerability Title
COVESA Open1722 0.9.2 Stack Buffer Overflow via avtp_to_can() in acf-can-listener
Source: CVE Program / CVE List V5
Vulnerability Description
COVESA Open1722 through 0.9.2 contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to write past the end of a fixed 15-slot stack array by sending a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtp_to_can() function increments its write index without bounding it against the caller-supplied array size, and because the listener accepts datagrams from any sender matching a hardcoded unauthenticated stream ID transmitted in plaintext, attackers can corrupt adjacent stack memory to achieve arbitrary code execution or denial of service.
