Tested on an MT7922 (mt7921e) with linux-firmware 20260810 - the image whose CLC region carries the idx 3 records - on a lockdep and UBSAN build of mainline at fd923b32d761, with 9417c5818a01 applied underneath. The device probes normally: the RAM firmware is loaded once rather than ten times, wlp11s0 appears, association with a 6 GHz AP works (channel 37, 6135 MHz, 160 MHz), and switching between a 5 GHz and a 6 GHz BSS and back is clean. No "hardware init failed", no "Invalid CLC record", and no UBSAN report - so the bounds checks are still doing their job on the very firmware that used to trip them. Tested-by: Mikhail Gavrilov One nit, take it or leave it: both length failures print the same "Invalid CLC record", so the log does not distinguish a table that ends mid-header from a record whose length is out of range. Two distinct strings would make a future report easier to read.
