{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\naccel/ivpu: Add bounds checks for firmware log indices\n\nAdd validation that read and write indices in the firmware log buffer\nare within valid bounds (< data_size) before using them. If\nout-of-bounds indices are encountered (from firmware), clamp them to\nsafe values instead of proceeding with invalid offsets.\n\nThis prevents potential out-of-bounds buffer access when firmware\nsupplies invalid log indices.",
