- Summary
- pinctrl: mcp23s08: Initialize mcp->dev and mcp->addr before regmap init
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: mcp23s08: Initialize mcp->dev and mcp->addr before regmap init
Regmap initialization triggers regcachemaplepopulate() 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 mcp23s08spiregmap_init() call.
