About this tag
The iso-tp can tag on WindowsForum.com covers discussions about the ISO-TP (ISO 15765-2) protocol for Controller Area Network (CAN) buses, particularly in the context of Linux kernel security. Recent content highlights a use-after-free vulnerability (CVE-2026-31474) in the Linux ISO-TP implementation, where a race condition in isotp_sendmsg can lead to early buffer freeing. This tag is relevant for developers, system administrators, and security researchers working with CAN bus systems, Linux kernel networking, or automotive software. Topics include kernel patches, socket lifecycle management, and CAN frame transmission. While the tag is Linux-focused, it may interest Windows users involved in cross-platform automotive or embedded development.
