CVE-2026-37538 Details
Description
Buffer overflow vulnerability in socketcand 0.4.2 in file socketcand.c in function main allows attackers to cause a denial of service or other unspecified impacts via crafted bus_name.
A buffer overflow vulnerability has been identified in socketcand version 0.4.2. The issue arises in the main function of socketcand.c, where the application copies a CAN frame identifier into a stack buffer without validating the length. This lack of proper input validation allows attackers to craft bus names that exceed the buffer size, leading to a stack buffer overflow. Such an overflow can cause a denial-of-service condition or other unspecified impacts.
