Local denial of service via unchecked allocation
Published Sep 18, 2024 · Updated May 11, 2026
NULL pointer dereference in the Linux kernel allows local users to crash affected systems during Intel SPI chip setup. intel_spi_populate_chip() stores the unchecked NULL return from devm_kasprintf() in pdata->name when name allocation fails. Reaching the flaw requires low-privileged local access, an affected kernel, the Intel SPI path, and an allocation failure; the reported consequence is availability loss without data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
