Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description
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.
