Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: Fix out-of-bounds read in dp_get_eq_aux_rd_interval()<br />
<br />
[Why & How]<br />
The aux_rd_interval array in struct dc_lttpr_caps is declared with<br />
MAX_REPEATER_CNT - 1 (7) elements, indexed 0..6. However, the offset<br />
parameter passed to dp_get_eq_aux_rd_interval() can be as large as<br />
MAX_REPEATER_CNT (8) when a sink reports 8 LTTPR repeaters via DPCD.<br />
This leads to an out-of-bounds read of aux_rd_interval[7] when offset<br />
is 8.<br />
<br />
Fix this by growing aux_rd_interval to MAX_REPEATER_CNT elements to<br />
accommodate the full range of valid repeater counts defined by the DP<br />
spec.<br />
<br />
(cherry picked from commit a55a458a8df37a65ffda5cf721d554a8f74f6b04)
