AI-suggested
A fix has been implemented in the Linux kernel by replacing unsafe string copy functions with safer alternatives that ensure proper zero padding. Users should apply the updated kernel versions that include this fix. Patch status is confirmed by the resolved vulnerability description.
Description
A vulnerability in the Linux kernel's TIPC protocol was resolved by correcting how interface name padding bytes are handled in RESET and ACTIVATE messages. The issue involved sending random pad bytes due to improper use of strcpy, which was replaced with memcpy and strscpy to ensure zero padding is sent instead of random data.
