checksum offload

About this tag
The checksum offload tag on WindowsForum.com covers discussions about hardware checksum offload, a performance feature in modern network interface controllers (NICs) that offloads checksum verification from the CPU. Content includes a Linux kernel fix (CVE-2025-40337) for the stmmac Ethernet driver, where Rx checksum offload results were mishandled, causing packets with hardware-reported checksum failures to be incorrectly marked as valid. This tag is relevant for users interested in networking, driver issues, and security vulnerabilities related to checksum offload implementations.

    Linux Kernel Stmmac RX Checksum Offload Fix CVE-2025-40337

    The Linux kernel received a targeted fix for a subtle but consequential networking error: CVE-2025-40337 corrects how the stmmac Ethernet driver handles Rx checksum offload results so that packets for which the hardware reported checksum failures are no longer marked as valid and passed up the...
