Description OSIDB Bzimport 2026-09-24 16:58:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

spi: Add NULL check for spi_get_device_id() in spi_get_device_match_data()

Prevent NULL pointer dereference when spi_get_device_id() returns NULL,
which can happen when using driver_override without matching SPI ID entry.
