CyberRota Analysis
AI-GeneratedA NULL pointer dereference vulnerability exists in the Linux kernel's EMAC driver, where an early interrupt can trigger a crash due to the improper ordering of resource mapping and interrupt request handling. This issue affects systems utilizing the EMAC driver, and organizations running Linux kernel versions that include this driver should prioritize applying the fix to prevent potential system instability.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: net: emac: Fix NULL pointer dereference in emac_probe Move devm_request_irq() after devm_platform_ioremap_resource() so that dev->emacp is mapped before the interrupt handler can fire. An early interrupt hitting emac_irq() would dereference the NULL dev->emacp and crash. Also remove redundant error message. devm_platform_ioremap_resource() already returns an error message with dev_err_probe().
