NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: ip6t_eui64: reject invalid MAC header for all packets

eui64_mt6() derives a modified EUI-64 from the Ethernet source address and compares it with the low 64 bits of the IPv6 source address.

The existing guard only rejects an invalid MAC header when par->fragoff != 0. For packets with par->fragoff == 0, eui64_mt6() can still reach eth_hdr(skb) even when the MAC header is not valid.

Fix this by removing the par->fragoff != 0 condition so that packets with an invalid MAC header are rejected before accessing eth_hdr(skb).
