Description
A flaw was found in the Linux kernel's igb driver. This vulnerability occurs when the driver processes network packets with large MAX_SKB_FRAG values, which are used to manage packet fragments. The driver fails to properly account for shared information size when selecting the ring layout, leading to two packets being stored in the same 4K memory page. This improper memory handling results in payload corruption during network transmission (TX), potentially allowing an attacker to cause data integrity issues.
