CVE-2026-46261 Details
Description
In the Linux kernel, the following vulnerability has been resolved: spi: wpcm-fiu: Fix potential NULL pointer dereference in wpcm_fiu_probe() platform_get_resource_byname() can return NULL, which would cause a crash when passed the pointer to resource_size(). Move the fiu->memory_size assignment after the error check for devm_ioremap_resource() to prevent the potential NULL pointer dereference.
A potential NULL pointer dereference vulnerability has been identified in the Linux kernel's SPI WPCM-FIU driver. The issue arises in the 'wpcm_fiu_probe()' function, where 'platform_get_resource_byname()' can return NULL. This NULL value, when passed to 'resource_size()', can lead to a crash. The vulnerability affects the Linux kernel stable tree.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability. The patches can be downloaded from the Linux kernel Git repository.
