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： 媒体子系统：verisilicon: hantro: 将 G2 HEVC 图块循环限制在缓冲区容量范围内 prepare_tile_info_buffer() 函数会将每个图块对应的一条信息写入 tile_sizes DMA 缓冲区，该缓冲区的大小是根据 PPS 用户空间接口（uAPI）数组容量所定义的网格来分配的。为此，引入使用 v4l2_hevc_pps_num_tile_columns() 和 v4l2_hevc_pps_num_tile_rows() 这两个辅助函数

Vulnerability Title
media: verisilicon: hantro: bound G2 HEVC tile loop to the buffer capacity
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
media: verisilicon: hantro: bound G2 HEVC tile loop to the buffer capacity
prepare_tile_info_buffer() writes one entry per tile into the tile_sizes
DMA buffer, sized for a grid equal to the PPS uAPI array capacity. Use the
bounded v4l2_hevc_pps_num_tile_columns() / v4l2_hevc_pps_num_tile_rows()
helpers so the loops stay inside the buffer.
