About this tag
The ETS offload tag covers discussions about the Enhanced Transmission Selection (ETS) traffic scheduler's hardware offload path in Linux. A notable thread examines CVE-2026-23379, a security vulnerability where a 32-bit integer overflow in the ETS offload code can cause a divide-by-zero panic, crashing the system. The fix involves switching key variables to 64-bit integers. This tag is relevant for system administrators, kernel developers, and IT professionals managing Linux networking, particularly those concerned with scheduler stability, hardware offload bugs, and kernel security patches. Topics include arithmetic overflow, weighted round-robin parameters, and upstream fixes for ETS offload issues.

    CVE-2026-23379 ETS Offload Bug: 32-bit Overflow Causes Divide-by-Zero Panic

    Linux’s latest scheduler-related security fix, CVE-2026-23379, is a reminder that even “small” arithmetic mistakes in kernel offload code can have outsized consequences. The flaw sits in the ETS traffic scheduler path, where the kernel computes weighted round-robin parameters for hardware...
