CVE-2026-53344

Description

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.
