"scenarios": [{"lang": "en", "value": "AV:L - The bug is reached via local iSCSI initiator session creation (NETLINK_ISCSI) and concurrent local sysfs reads of the host ipaddress attribute, not by processing packets from a remote peer.\nAC:L - The attacker can induce memory pressure so iscsi_tcp_r2tpool_alloc() fails and concurrently hammer the world-readable sysfs ipaddress path, controlling the reader side of the race (and both sides if also creating sessions).\nPR:L - show_host_param_ISCSI_HOST_PARAM_IPADDRESS is S_IRUGO with no capability check, so an unprivileged local user can trigger the UAF while iscsid performs session create; CAP_SYS_ADMIN is only required for the netlink create side, not the sysfs exploit path.\nUI:N - No separate victim user action is required; the attacker only needs to read sysfs while session creation/teardown occurs on the system.\nS:U - This is a standard in-kernel UAF/privilege-escalation impact within the same host security authority, with no VM, IOMMU, or other cross-boundary escape.\nC:H - The UAF lets userspace operate on a freed iscsi_session (including lock and field access), which can be turned into an arbitrary kernel read via heap reuse.\nI:H - The UAF path takes spin_lock_bh on freed session memory (write to freed object), enabling heap spraying and control-flow hijacking primitives.\nA:H - Dereferencing/locking the freed session causes kernel oops/panic as demonstrated by the related KASAN UAF report, so availability impact is high."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus":
