Description

A flaw was found in the Linux kernel's networking subsystem. Specifically, the kernel incorrectly processes transmit errors for Generic Segmentation Offload (GSO) frames. When a single segment within a GSO frame is lost, the system may misinterpret this as a complete loss of the entire frame. This can lead to Transmission Control Protocol (TCP) connections becoming unresponsive, resulting in a Denial of Service (DoS) for network communications.
