This case is not checked in the code and\nwith an appropriately crafted netlink message, an out-of-bounds read of up\nto 64 bytes (max secret length) can occur past the skb end pointer and into\nskb_shared_info:\n\nBreakpoint 1, seg6_genl_sethmac (skb=\u003coptimized out\u003e, info=\u003coptimized out\u003e) at net/ipv6/seg6.c:208\n208\t\tmemcpy(hinfo-\u003esecret, secret, slen);\n(gdb) bt\n #0 seg6_genl_sethmac (skb=\u003coptimized out\u003e, info=\u003coptimized out\u003e) at net/ipv6/seg6.c:208\n #1 0xffffffff81e012e9 in genl_family_rcv_msg_doit (skb=skb@entry=0xffff88800b1f9f00, nlh=nlh@entry=0xffff88800b1b7600,\n extack=extack@entry=0xffffc90000ba7af0, ops=ops@entry=0xffffc90000ba7a80, hdrlen=4, net=0xffffffff84237580 \u003cinit_net\u003e, family=\u003coptimized out\u003e,\n family=\u003coptimized out\u003e) at net/netlink/genetlink.c:731\n #2 0xffffffff81e01435 in genl_family_rcv_msg (extack=0xffffc90000ba7af0, nlh=0xffff88800b1b7600, skb=0xffff88800b1f9f00,\n family=0xffffffff82fef6c0 \u003cseg6_genl_family\u003e) at net/netlink/genetlink.c:775\n #3 genl_rcv_msg (skb=0xffff88800b1f9f00, nlh=0xffff88800b1b7600, extack=0xffffc90000ba7af0) at net/netlink/genetlink.c:792\n #4 0xffffffff81dfffc3 in netlink_rcv_skb (skb=skb@entry=0xffff88800b1f9f00, cb=cb@entry=0xffffffff81e01350 \u003cgenl_rcv_msg\u003e)\n at net/netlink/af_netlink.c:2501\n #5 0xffffffff81e00919 in genl_rcv (skb=0xffff88800b1f9f00) at net/netlink/genetlink.c:803\n #6 0xffffffff81dff6ae in netlink_unicast_kernel (ssk=0xffff888010eec800, skb=0xffff88800b1f9f00, sk=0xffff888004aed000)\n at net/netlink/af_netlink.c:1319\n #7 netlink_unicast (ssk=ssk@entry=0xffff888010eec800, skb=skb@entry=0xffff88800b1f9f00, portid=portid@entry=0, nonblock=\u003coptimized out\u003e)\n at net/netlink/af_netlink.c:1345\n #8 0xffffffff81dff9a4 in netlink_sendmsg (sock=\u003coptimized out\u003e, msg=0xffffc90000ba7e48, len=\u003coptimized out\u003e) at net/netlink/af_netlink.c:1921\n...\n(gdb) p/x ((struct sk_buff *)0xffff88800b1f9f00)-\u003ehead + ((struct sk_buff *)0xffff88800b1f9f00)-\u003eend\n$1 = 0xffff88800b1b76c0\n(gdb) p/x secret\n$2 = 0xffff88800b1b76c0\n(gdb) p slen\n$3 = 64 \u0027@\u0027\n\nThe OOB data can then be read back from userspace by dumping HMAC state.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
