"value": "AV:L - The vulnerable parser is reached through the local DRM connector-probe path (`DRM_IOCTL_MODE_GETCONNECTOR` → `drm_helper_probe_single_connector_modes` → `amdgpu_dm_connector_get_modes`/`dm_dp_mst_get_modes` → `amdgpu_dm_update_freesync_caps`), requiring access to `/dev/dri/card0` rather than any network or physical-device interaction. No attacker-supplied monitor is needed since the out-of-bounds read occurs for ordinary EDIDs.\nAC:L - The overread is unconditional for any EDID containing an extension block without an AMD VSDB v3 entry — the loop always walks j to 127 — so it triggers reliably on every probe with no race, timing window, or attacker-uncontrollable precondition.\nPR:L - An unprivileged local user with a normal desktop session (logind ACL / `video` group access to the primary DRM node) can trigger connector re-probes; `DRM_IOCTL_MODE_GETCONNECTOR` is registered with flags 0 and needs no root or CAP_SYS_ADMIN.\nUI:N - Connector probing happens automatically at boot, on hotplug, and via the DRM poll loop, and can be driven directly by the attacker's own ioctls; no action by another user is required.\nS:U - The out-of-bounds access stays within the kernel's own heap and security authority, with no crossing into a hypervisor, IOMMU, or other protection domain.\nC:H - Adjacent slab memory beyond the EDID allocation is read into `ieeeId`/`version`/`feature_caps`, and consistent with this CNA's scoring of the analogous EDID out-of-bounds read (CVE-2026-64546) the disclosure of heap contents past the object boundary is treated as High.\nI:L - There is no out-of-bounds write, but a local attacker who heap-grooms the neighbouring object so the leaked bytes match AMD's IEEE ID and version 3 can force `vsdb_info->replay_mode` and `as_type = ADAPTIVE_SYNC_TYPE_EDP`, making the driver program Replay on a panel that never advertised it — a bounded, unauthorized modification of driver state.\nA:H - The slab out-of-bounds read faults immediately on KASAN/hardened builds and can hit an unmapped page when the EDID allocation ends on a page boundary, producing a kernel oops during connector probe."
