This is the same defect\nas the F3A handler, which was copied from F30.\n\nSize the keymap for the full gpioled_count; the mapping loop still\nassigns only the first min(gpioled_count, TRACKSTICK_RANGE_END) entries."

No race or condition outside the attacker's control is required.\nPR:L - The evdev ioctl path contains no capability or namespace privilege check, so any ordinary user permitted to open the event node can trigger it.\nUI:N - The attacker directly issues the ioctls, and the separate attention path is device-driven; neither requires action by another user.\nS:U - The vulnerable driver and the affected kernel memory share the same security authority. Kernel privilege escalation or code execution does not itself cross a VM, IOMMU, or other scope boundary.\nC:H - EVIOCGKEYCODE returns attacker-selected out-of-bounds u16 values and can disclose multiple adjacent slab words across the available indices. This heap disclosure can expose security-sensitive kernel data and facilitate further exploitation.\nI:H - EVIOCSKEYCODE performs attacker-controlled u16 writes beyond the allocation at selectable offsets. These writes can corrupt adjacent heap objects or metadata and plausibly enable control-flow hijacking.\nA:H - The controlled heap corruption can damage adjacent kernel objects and cause an oops or panic, while the device can also repeatedly trigger the out-of-bounds attention path."
