  "description": "In the Linux kernel, the following vulnerability has been resolved:  media: rkvdec: hevc: guard INTER_REF_PIC_SET_PRED index underflow  st_ref_pic_set_prediction() computes the reference RPS index as st_rps_idx - (delta_idx_minus1 \u002B 1) per HEVC spec equation 7-59. Both operands are u8, so when delta_idx_minus1 \u002B 1 exceeds the current index the subtraction wraps and the subsequent array access at calculated_rps_st_sets[ref_rps_idx] reads far out of bounds.  A userspace V4L2 client that can open the RKVDEC m2m decoder can submit an EXT_SPS_ST_RPS control with INTER_REF_PIC_SET_PRED set and delta_idx_minus1 crafted to trigger the underflow.  Reject the entry early when the reference index would underflow.",
