CVE-2026-98363 is a vulnerability in Linux Kernel
Published on October 6, 2026
firmware: arm_scpi: reject DVFS OPP count above MAX_DVFS_OPPS
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scpi: reject DVFS OPP count above MAX_DVFS_OPPS
scpi_dvfs_get_info() already rejected a zero opp_count, but still trusted
any larger value from the SCP firmware. The shared-memory reply only holds
MAX_DVFS_OPPS entries in buf.opps[]; a bigger count over-reads that array
and then sizes the allocated OPP table incorrectly (garbage OPPs / OOB).
The missing upper bound dates back to the original SCPI DVFS support.
Reject zero and out-of-range counts in one check and return -EINVAL.
