In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/amd\/display: Fix out-of-bounds read in dp_get_eq_aux_rd_interval()<\/p>\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.<\/p>\n
Fix 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.<\/p>\n
