CVE-2017-7477 (GCVE-0-2017-7477)

Vulnerability from cvelistv5 – Published: 2017-04-25 14:00 – Updated: 2024-08-05 16:04

Summary

Heap-based buffer overflow in drivers/net/macsec.c in the MACsec module in the Linux kernel through 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, leading to an error in the skb_to_sgvec function.

Severity

No CVSS data available.

CWE

heap overflow
