CVE-2025-51823 (GCVE-0-2025-51823)

Vulnerability from cvelistv5 – Published: 2025-08-11 00:00 – Updated: 2025-08-11 19:27

Summary

libcsp 2.0 is vulnerable to Buffer Overflow in the csp_eth_init() function due to improper handling of the ifname parameter. The function uses strcpy to copy the interface name into a structure member (ctx->name) without validating the input length.

Severity

6.5 (Medium)
