CVE-2026-64277 is an out-of-bounds memory-access vulnerability in the Linux kernel Synaptics RMI4 input driver's F3A keymap handling. The driver accepts a device-reported GPIO count of up to 127, but allocated its GPIO keymap for no more than six entries. The attention handler subsequently iterated over the full reported count, causing out-of-bounds reads when the count exceeded six. Additionally, the input device keycode maximum reflected the full GPIO count despite the smaller backing allocation. Consequently, default evdev keymap ioctl handlers could access memory beyond the keymap because they validated indexes against the reported maximum rather than the allocation size. The fix allocates the keymap for the complete reported GPIO count; entries beyond the supported trackstick mapping range remain KEY_RESERVED.
