UBUNTU-CVE-2025-38408: High severity ubuntu/linux-hwe-edge vulnerability

Q: Which Ubuntu kernel packages are identified as affected?

The affected packages listed are linux-azure-fde, linux-realtime, linux-azure, linux-gcp, linux-gke, linux-gkeop, linux-riscv, and linux-aws-fips.

Q: What level of access does an attacker need?

The severity vector indicates local access, low attack complexity, low privileges required, and no user interaction. The impact is denial of service through invalid pointer dereferencing, with no listed confidentiality or integrity impact.

Q: What is the underlying failure condition?

Simulation work contexts were allocated with kmalloc(), leaving ops member pointers with random contents. Those uninitialized pointers could later be dereferenced; the fix uses kzalloc() to initialize the allocation.

Published Jul 25, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: genirq/irqsim: 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.

Frequently Asked Questions

Which Ubuntu kernel packages are identified as affected?

The affected packages listed are linux-azure-fde, linux-realtime, linux-azure, linux-gcp, linux-gke, linux-gkeop, linux-riscv, and linux-aws-fips.

What level of access does an attacker need?

The severity vector indicates local access, low attack complexity, low privileges required, and no user interaction. The impact is denial of service through invalid pointer dereferencing, with no listed confidentiality or integrity impact.

What is the underlying failure condition?

Simulation work contexts were allocated with kmalloc(), leaving ops member pointers with random contents. Those uninitialized pointers could later be dereferenced; the fix uses kzalloc() to initialize the allocation.
