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： clk: scpi: 在 scpi_dvfs_recalc_rate 中对 DVFS 索引进行边界检查 如果 SCP 固件存在缺陷或返回了过时（stale）值， 可能返回超出范围的索引。此前仅拒绝了负数索引，因此较大的索引会越界访问 ，导致将垃圾数据误认为时钟频率（引发 KASAN 越界访问/向消费者报告错误的频率）。这一缺失的上界检查问题可追溯至原始的 SCPI 时钟驱动。 现在将大于等于 OPP 计数的索引视为无效，并返回 0，处理方式与索引小于 0 时相同。

Vulnerability Title
clk: scpi: bound-check DVFS index in scpi_dvfs_recalc_rate
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
clk: scpi: bound-check DVFS index in scpi_dvfs_recalc_rate
dvfs_get_idx() may return an out-of-range index if the SCP firmware is
buggy or returns a stale value. Only negative indexes were rejected, so a
large index walked past info->opps and could treat garbage as a clock rate
(KASAN OOB / wrong frequency to consumers). The missing upper bound dates
back to the original SCPI clock driver.
Treat indexes >= opp count as invalid and return 0, same as idx < 0.
