Official 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.
Technical Analysis
CVE-2026-53344 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
