Laxman Acharya PadhyaandFelix Fietkau 6ff6004fdb wifi: mt76: mt7921: validate CLC firmware records
The CLC region is supplied by firmware, but the loader trusts the
region count and each record length. A malformed image can make the
region table pointer precede the firmware buffer, make the record loop
fail to advance, or index phy->clc past its end. Validate the table and
record bounds before dereferencing or copying.
