CVE-2025-38408: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: from 5.8, before 6.12.37 (fixed in 6.12.37); from 6.13, before 6.15.6 (fixed in 6.15.6); version 6.16 only
