Input Handling Issue in Linux Kernel Affects Psxpad SPI Driver

CVE-2026-80752

What is CVE-2026-80752?

A vulnerability exists in the Linux kernel related to the Psxpad SPI driver. This issue arises when the driver attempts to retrieve controller state information using the spi_get_drvdata() function during the suspension process. However, because the necessary data is not stored during the probe, the function inadvertently dereferences a NULL pointer. This flaw could lead to unexpected behavior or crashes. Developers are urged to ensure that data is properly managed during the driver's probe to avoid similar issues in the future.
