CVE-2025-38408

CVE-2025-38408 pertains to the Linux kernel’s genirq/irq_sim component. The issue arises from improper initialization of the simulation work context pointers in the ops structure, where pointers were allocated with kmalloc() and could contain random content, risking invalid dereferencing. The doc...
