Vulnerability from fkie_nvd - Published: 2026-02-04 17:16 - Updated: 2026-03-13 21:27

Severity ?

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

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.

However, since the\ncontroller was registered via a devm function, the device core will\nautomatically call spi_controller_put() again when the probe fails.\nThis results in a double-free of the spi_controller structure.\n\nFix this by switching to devm_spi_alloc_host() and removing the\nmanual spi_controller_put() call."
