Vulnerability from github – Published: 2026-09-03 15:32 – Updated: 2026-09-04 06:31

Details

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

Input: psxpad-spi - set driver data before use

psxpad_spi_suspend() retrieves the controller state with spi_get_drvdata(), but probe never stores it, so suspend dereferences a NULL pointer. Store it during probe.

Severity

8.4 (High)
