CVE-2025-38408 Details
Description
In the Linux kernel, the following vulnerability has been resolved: genirq/irq_sim: Initialize work context pointers properly Initialize `ops` member's pointers properly by using kzalloc() instead of kmalloc() when allocating the simulation work context. Otherwise the pointers contain random content leading to invalid dereferencing.
A vulnerability in the Linux kernel's genirq/irq_sim component was addressed by properly initializing work context pointer members. The issue arose because the pointers were allocated with kmalloc(), which left them with random, undefined content. This improper initialization could lead to invalid memory dereferences.
