About this tag
The kernel TLS tag on WindowsForum.com covers discussions about the Linux kernel's Transport Layer Security (TLS) implementation, particularly security vulnerabilities and bug fixes. Recent content focuses on CVE-2026-23240, a race condition in the kernel TLS code that could allow a worker to dereference a freed TLS object. The fix involves replacing cancel_delayed_work_sync() with disable_delayed_work_sync() to prevent re-queueing of delayed work. While the tag is Linux-specific, it may interest Windows users who work with cross-platform systems, containers, or kernel-level networking. The tag provides technical details on kernel TLS patches and their implications for system stability and security.

    Linux Kernel TLS Race Fix CVE-2026-23240: Use disable_delayed_work_sync

    The Linux kernel has received a small but important patch that fixes a timing (race) bug in the kernel TLS implementation: CVE-2026-23240 addresses a race in tls_sw_cancel_work_tx() where a worker can be scheduled after the kernel believes the delayed work has been cancelled, allowing the worker...
