CVE-2025-53888 (CNNVD-202507-2440)
中文标题:
RIOT 安全漏洞
英文标题:
RIOT-OS has an ineffective size check that can lead to buffer overflow in link layer address filter /sys/net/link_layer/l2filter/l2filter.c
漏洞描述
中文描述:
RIOT是RIOT开源的一套应用于物联网领域的操作系统。 RIOT 2025.04及之前版本存在安全漏洞，该漏洞源于无效的大小检查，可能导致缓冲区溢出。
英文描述:
RIOT-OS, an operating system that supports Internet of Things devices, has an ineffective size check implemented with `assert()` can lead to buffer overflow in versions up to and including 2025.04. Assertions are usually compiled out in production builds. If assertions are the only defense against untrusted inputs, the software may be exposed to attacks that utilize the lack of proper input checks. In the `l2filter_add()` function shown below, `addr_len` is checked using an assertion and is subsequently used as an argument in a `memcpy()` call. When assertions are disabled, there would be no size check for `addr_len`. As a consequence, if an attacker were to provide an `addr_len` value larger than `CONFIG_L2FILTER_ADDR_MAXLEN`, they can trigger a buffer overflow and write past the `list[i].addr` buffer. If the unchecked input is attacker-controlled, the impact of the buffer overflow can range from a denial of service to arbitrary code execution. Commit f6f7de4ccc107c018630e4c15500825caf02e1c2 contains a patch for the vulnerability.
