Vulnerability from github – Published: 2026-02-04 18:30 – Updated: 2026-02-06 18:30

Details

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

spi: spi-sprd-adi: Fix double free in probe error path

The driver currently uses spi_alloc_host() to allocate the controller but registers it using devm_spi_register_controller().

If devm_register_restart_handler() fails, the code jumps to the put_ctlr label and calls spi_controller_put(). However, since the controller was registered via a devm function, the device core will automatically call spi_controller_put() again when the probe fails. This results in a double-free of the spi_controller structure.

Fix this by switching to devm_spi_alloc_host() and removing the manual spi_controller_put() call.
