About this tag
The espintcp tag on WindowsForum.com covers discussions about the Linux kernel's TCP encapsulation for IPsec, specifically the espintcp module. Recent content focuses on a race condition vulnerability (CVE-2026-23239) in the espintcp code, where a patch replaces cancel_work_sync() with disable_work_sync() in espintcp_close() to prevent worker threads from accessing freed context during socket teardown. This tag is relevant for developers and system administrators working with Linux kernel networking, IPsec, and security patches. Topics include kernel race conditions, TCP encapsulation, and the espintcp implementation.
