  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/gud: fix out-of-bounds write in gud_plane_atomic_check()\n\nThe plane property loop uses req-\u003eproperties[num_properties + i] as write\nindex while simultaneously incrementing `num_properties` inside the loop.\nAt iteration i, num_properties has also incremented by i, so the write\nis done at `initial_num_properties + 2*i`, skipping every other index and\nadvancing by 2 per iteration.\n\nWith just 2 connector and 32 plane properties the last write happens at\nindex 64, one slot past the end of the 64-slot (indices 0–63)\nallocation. A USB device can trigger OOB by advertising the maximum\nnumber of properties.\n\nFix by dropping the redundant `+ i`; num_properties is already the correct\nrunning index, as gud_connector_fill_properties() fills the preceding\nslots.",
