      "title": "ieee802154: admin-gate legacy LLSEC dump operations",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nieee802154: admin-gate legacy LLSEC dump operations\n\nIn net/ieee802154/netlink.c, the legacy IEEE802154_NL family ops table\nbuilds the LLSEC dump entries (LLSEC_LIST_KEY, LLSEC_LIST_DEV,\nLLSEC_LIST_DEVKEY, LLSEC_LIST_SECLEVEL) with IEEE802154_DUMP() which\nsets no .flags, so generic netlink runs them ungated. The modern\nnl802154 family admin-gates the equivalent reads via\nNL802154_CMD_GET_SEC_KEY and friends with .flags = GENL_ADMIN_PERM.\n\nAny local uid that can open AF_NETLINK / NETLINK_GENERIC can resolve\nthe \"802.15.4 MAC\" family and dump LLSEC_LIST_KEY on any wpan netdev\nthat has an LLSEC key installed; the dump handler writes the raw\n16-byte AES-128 key bytes (IEEE802154_ATTR_LLSEC_KEY_BYTES, copied\nverbatim from struct ieee802154_llsec_key.key) into the reply.\nRecovering the AES key compromises 802.15.4 LLSEC link confidentiality\nand authenticity, since LLSEC uses CCM* and the same key authenticates\nand encrypts frames.\n\nImpact: any local uid with no capabilities can read the raw 16-byte\nAES-128 LLSEC key from the kernel keytable on any wpan netdev that has\nan administrator-installed LLSEC key, by issuing an LLSEC_LIST_KEY\ndump on the legacy IEEE802154_NL generic-netlink family.\n\nIntroduce IEEE802154_DUMP_PRIV() mirroring IEEE802154_DUMP() but\nsetting .flags = GENL_ADMIN_PERM, and use it for the four LLSEC dump\nentries. LIST_PHY and LIST_IFACE retain IEEE802154_DUMP() because the\nmodern nl802154 family exposes their equivalents to unprivileged\nreaders by design (NL802154_CMD_GET_WPAN_PHY and\nNL802154_CMD_GET_INTERFACE carry \"can be retrieved by unprivileged\nusers\" annotations).",
