"value": "AV:L - The vulnerability is triggered through the ethtool generic-netlink command ETHTOOL_MSG_MODULE_FW_FLASH_ACT issued over an AF_NETLINK socket, which requires local system access. No remote or adjacent-network packet path reaches `ethtool_cmis_module_poll()`.\nAC:L - The wrong size is used unconditionally on every poll iteration, so any firmware-flash request against a CMIS module reliably produces the 7-byte stack overwrite and stack-protector panic — no race to win and no memory-layout precondition outside the attacker's control.\nPR:L - The netlink op is gated by GENL_UNS_ADMIN_PERM, i.e. `netlink_ns_capable(skb, net->user_ns, CAP_NET_ADMIN)`, which an unprivileged user can obtain in their own user/network namespace via `unshare -Urn`, so this is namespace-scoped CAP_NET_ADMIN rather than real init-namespace root.\nUI:N - The attacker issues the module firmware-flash request directly and the crash occurs in the resulting kworker; no victim action, mount, or file-open by another user is needed.\nS:U - The stack corruption occurs in kernel context and its impact stays within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is an out-of-bounds kernel stack write whose contents come from an attacker-influenceable transceiver EEPROM, and corrupting saved locals/return state in `ethtool_cmis_wait_for_cond()` is leverageable toward arbitrary kernel memory disclosure on configurations without an effective stack canary.\nI:H - A 7-byte out-of-bounds stack write with externally supplied data is direct kernel memory corruption; per out-of-bounds-write guidance this is High, as adjacent stack state can be overwritten to influence control flow.\nA:H - The reported and reproducible outcome is `Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in ethtool_cmis_wait_for_cond`, an immediate unrecoverable system crash from a kernel worker thread."
