In the Linux kernel, the following vulnerability has been resolved:

rtw89: cfo: check mac_id to avoid out-of-bounds

Somehow, hardware reports incorrect mac_id and pollute memory. Check index
before we access the array.

  UBSAN: array-index-out-of-bounds in rtw89/phy.c:2517:23
  index 188 is out of range for type 's32 [64]'
  CPU: 1 PID: 51550 Comm: irq/35-rtw89_pc Tainted: G           OE
