AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel by adding a NULL check in spi_get_device_match_data(). Users should apply the official kernel updates that include this fix. Patch status is not explicitly confirmed in the provided data, so users should consult the vendor advisory or distribution security updates for the specific fixed versions.
Description
A vulnerability in the Linux kernel's SPI subsystem was resolved by adding a NULL check in spi_get_device_match_data() to prevent a NULL pointer dereference when spi_get_device_id() returns NULL. This condition can occur when using driver_override without a matching SPI ID entry. The issue affects specific Linux kernel versions and has a medium severity rating.
