CVE-2026-53330

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 &amp; 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)
