CVE-2026-98097 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: tipc: Dont send random pad bytes in RESET/ACTIVATE messages The interface name is passed in a fixed length (TIPC_MAX_IF_NAME) buffer. Replace the strcpy(data, l->if_name) with memcpy() so that the pad bytes are actually written (l->if_name[] is zero padded) rather than sending random bytes from the skb to the remote system. Replace two other strcpy() with strscpy().. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
