In the Linux kernel, the following vulnerability has been resolved:
pinctrl: mcp23s08: Initialize mcp->dev and mcp->addr before regmap init
Regmap initialization triggers regcache maple populate() which attempts
SPI read to populate cache. SPI read requires mcp->dev and mcp->addr to
be set, without them, NULL pointer dereference occurs during probe.
Move initialization before mcp23s08 spi regmap init() call.
