Vulnerability from fkie_nvd - Published: 2025-07-25 14:15 - Updated: 2026-01-11 17:15
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.
