"value": "AV:L - The vulnerable path is reached through a generic netlink socket (VDPA_CMD_MGMTDEV_GET on the vdpa genl family), which requires local system access. Per kernel scoring guidance, netlink-reachable code is Local.\nAC:L - The out-of-bounds read is fully deterministic — every MGMTDEV_GET doit or dump against a vp_vdpa management device walks past the single-entry allocation with no race, timing window, or attacker-uninfluenceable memory layout required.\nPR:L - VDPA_CMD_MGMTDEV_GET is registered without GENL_ADMIN_PERM (drivers/vdpa/vdpa.c:1544), unlike the sibling DEV_NEW/DEV_DEL/DEV_ATTR_SET ops, so any unprivileged local user can trigger the read and receive the reply; the dump variant needs no attributes at all.\nUI:N - The attacker triggers the bug entirely on their own by sending a netlink message; no victim action or cooperation is involved.\nS:U - The out-of-bounds read stays within the kernel's own heap and the impact is confined to the kernel security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The read is unbounded — it walks adjacent slab memory until it chances upon a zero word — and the derived value is returned to the unprivileged caller in VDPA_ATTR_DEV_MGMTDEV_SUPPORTED_CLASSES, disclosing adjacent heap contents rather than a strictly bounded few bytes.\nI:L - Garbage device IDs harvested out of bounds are folded into the classes bitmask and ncls counter that gate the class-consistency validation in vdpa_nl_cmd_dev_add_set_doit(), so out-of-bounds heap data can alter kernel device-creation decisions in a limited way.\nA:H - The unterminated walk can run far past the object into a non-present region and oops the kernel, and on KASAN-instrumented builds the slab-out-of-bounds report panics under panic_on_warn; the read is repeatable at will by an unprivileged user."
