CVE-2024-45030

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the igb driver in the Linux kernel, which does not handle large MAX SKB FRAGS values properly. Setting MAX SKB FRAG to 45 causes payload corruption on TX. The root cause of the issue is that the driver does not take into account properly the shared info size when selecting the ring layout, and will try to fit two packets inside the same 4K page even when the 1st fraglist will trump over the 2nd head. An easy reproducer is to run ssh to connect to the machine, which works with MAX SKB FRAGS=17 but fails with MAX SKB FRAGS=45.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
