CVE-2026-98362

/// Technical 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.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
