AI-suggested

A fix is available in multiple Linux kernel commits identified by the provided fixedVersions hashes. Users should update to a Linux kernel version including these commits to remediate the vulnerability.

Description

A vulnerability in the Linux kernel's arm_scpi firmware interface allowed the DVFS OPP count to exceed the maximum allowed, causing out-of-bounds array access and incorrect sizing of the OPP table. This flaw was fixed by rejecting zero and out-of-range counts, returning an error instead.
