Summary

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

spi: cadence: Fix out-of-bounds array access in cdns_mrvl_xspi_setup_clock()

If requested_clk > 128, cdns_mrvl_xspi_setup_clock() iterates over the entire cdns_mrvl_xspi_clk_div_list array without breaking out early, causing 'i' to go beyond the array bounds.

Fix that by stopping the loop when it gets to the last entry, clamping the clock to the minimum 6.25 MHz.

Fixes the following warning with an UBSAN kernel:

vmlinux.o: warning: objtool: cdns_mrvl_xspi_setup_clock: unexpected end of section .text.cdns_mrvl_xspi_setup_clock
