Summary

A heap-based buffer overflow in the MACsec module in the Linux kernel through version 4.10.12 allows attackers to cause a denial of service or possibly have unspecified other impact by leveraging the use of a MAX_SKB_FRAGS+1 size in conjunction with the NETIF_F_FRAGLIST feature.

Risk Assessment

Organizations may be exposed to denial of service and other unspecified threats, potentially disrupting the operation of systems based on the Linux kernel. Exploiting this vulnerability could have serious consequences for service availability.
