Hello,
I tried to reproduce, but unfortunately, it didn't, and the dmesg log as
attachment.
I had enabled CONFIG_KASAN and CONFIG_SLUB_DEBUG_ON configs.
Can you describe the flow of your operation?
Thanks.

In order to make pl011 work better, multiple interrupts are
required, such as TXIM, RXIM, RTIM, error interrupt(FE/PE/BE/OE);
at the same time, pl011 to GIC does not merge the interrupt
lines(each serial-interrupt corresponding to different GIC hardware
interrupt), so need to enable and request multiple gic interrupt
numbers in the driver.

This could trigger a slab-out-of-bounds during booting.
