CVE-2026-97580— media: rkvdec: bound HEVC tile loops and PPS id to the array capacity

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： media: rkvdec：限制 HEVC 瓦片循环和 PPS ID 的范围至数组容量 函数 和 会遍历由 / 决定的条目数量，而 会为每个瓦片写入一个 COLUMN_WIDTH / ROW_HEIGHT 寄存器，并使用 作为索引访问 数组。这些值均取自不可信的 PPS（图像参数集）。 应使用有界辅助函数 / 来约束瓦片循环的范围，并在 中，当 超出范围时，在索引 之前就提前退出，从而确保写入操作始终限制在硬件表的有效范围内。

Vulnerability Title
media: rkvdec: bound HEVC tile loops and PPS id to the array capacity
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: media: rkvdec: bound HEVC tile loops and PPS id to the array capacity compute_tiles_uniform() and compute_tiles_non_uniform() loop over num_tile_columns_minus1 + 1 / num_tile_rows_minus1 + 1 entries, and assemble_hw_pps() writes one COLUMN_WIDTH / ROW_HEIGHT register per tile and indexes priv_tbl->param_set[] by pic_parameter_set_id, all taken from the untrusted PPS. Use the bounded v4l2_hevc_pps_num_tile_columns() / v4l2_hevc_pps_num_tile_rows() helpers for the tile loops, and bail out of assemble_hw_pps() before indexing priv_tbl->param_set[] with an out-of-range pic_parameter_set_id, so the writes stay within the hardware tables.
