UBUNTU-CVE-2025-21665: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: Which systems are exposed to this issue?

The issue affects 32-bit kernels in the listed Ubuntu kernel packages when writing to an XFS filesystem. The affected package set includes linux-realtime, linux-azure, linux-gcp, linux-gke, linux-gkeop, linux-riscv, linux-fips, and linux-hwe-edge.

Q: What is required to trigger the problem?

A local attacker needs low privileges and must be able to cause writes to an XFS filesystem on an affected 32-bit kernel. Successful triggering can lead to an infinite loop, affecting availability.
