CVE-2021-46993

CVE-2021-46993 — Linux kernel sched: out-of-bounds access in uclamp bucket calculation. Util-clamp places tasks into buckets based on clamp values; with, e.g., 20 buckets, bucket size computed as 1024/20=51 can map a clamp of 1024 to bucket id 20, while valid indexes are 0–19, causing OOB access....
