CVE-2026-80575

CVE-2026-80575 affects the cs40l50-vibra Linux kernel input driver (a haptic vibration controller). The function cs40l50_add() copies user-supplied custom_data from an FF_PERIODIC/FF_CUSTOM effect via the EVIOCSFF ioctl without sufficient validation. Three distinct issues exist: custom_len == 0 c...
