Description

spi: fsl-qspi: use devm function instead of driver remove

In the Linux kernel, the following vulnerability has been resolved:

spi: fsl-qspi: use devm function instead of driver remove

Driver use devm APIs to manage clk/irq/resources and register the spi

controller, but the legacy remove function will be called first during

device detach and trigger kernel panic. Drop the remove function and use

devm_add_action_or_reset() for driver cleanup to ensure the release

sequence.

Trigger kernel panic on i.MX8MQ by

echo 30bb0000.spi >/sys/bus/platform/drivers/fsl-quadspi/unbind

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
