"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Fix out-of-bounds read in dp_get_eq_aux_rd_interval()\n\n[Why & How]\nThe aux_rd_interval array in struct dc_lttpr_caps is declared with\nMAX_REPEATER_CNT - 1 (7) elements, indexed 0..6. However, the offset\nparameter passed to dp_get_eq_aux_rd_interval() can be as large as\nMAX_REPEATER_CNT (8) when a sink reports 8 LTTPR repeaters via DPCD.\nThis leads to an out-of-bounds read of aux_rd_interval[7] when offset\nis 8.\n\nFix this by growing aux_rd_interval to MAX_REPEATER_CNT elements to\naccommodate the full range of valid repeater counts defined by the DP\nspec.\n\n(cherry picked from commit a55a458a8df37a65ffda5cf721d554a8f74f6b04)"
