The required clone/CT action graph is locally configured; no routable protocol message alone creates it.\nAC:L - The attacker controls the packet clones, competing same-zone commits, helper payload, and label-setting commit; parallel repeated executes can make the helper-bearing clone lose confirmation and relocate the extension block. Both sides of the race and heap grooming are attacker-controlled.\nPR:L - dp_packet_genl_ops marks OVS_PACKET_CMD_EXECUTE with GENL_UNS_ADMIN_PERM, which genl_family_rcv_msg checks as CAP_NET_ADMIN in net->user_ns. An ordinary user can obtain that capability in a new user and network namespace, so init-namespace root is unnecessary.\nUI:N - After creating a private OVS datapath, the attacker\u2019s own Netlink execute requests and injected packets drive the clone and commit sequence; no victim must configure, open, or approve anything.\nS:U - The stale nf_conn extension pointer and resulting writes affect the same host kernel that processes the attacker\u2019s OVS actions; escalating from a user namespace into that kernel does not cross a CVSS security scope.\nC:H - nf_ct_ext_add() can krealloc and free the old block containing nf_conn_help while an expectation retains pointers into it. Reclaiming that block turns the teardown UAF into groomable kernel-object corruption that can support kernel-memory disclosure.\nI:H - nf_ct_remove_expectations() calls hlist_del_rcu(), whose __hlist_del() writes through exp->lnode.pprev into freed or reused extension memory. This is attacker-groomable kernel heap corruption capable of control-flow hijacking.\nA:H - The stale pprev write during expectation destruction can corrupt a reclaimed kernel object and cause an oops or panic, taking down the host kernel."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
