kernel: Linux kernel: Use-After-Free in net/gro due to improper handling of zerocopy skbs

A flaw was found in the Linux kernel's Generic Receive Offload GRO networking subsystem. This vulnerability occurs when skbgroreceive attempts to merge zerocopy socket buffers skbs without properly managing page reference counts, specifically when the SKBFLMANAGEDFRAGREFS flag is set. An attacker...
