UBUNTU-CVE-2026-72100: High severity ubuntu/linux-hwe-edge vulnerability

Q: What access does an attacker need to exploit this issue?

The vulnerability is rated network-accessible with low attack complexity, but it requires low-level privileges. No user interaction is required.

Q: What is the likely impact if exploitation succeeds?

Successful exploitation can affect confidentiality, integrity, and availability at a high level. The specific flaw can leave a dm-integrity range locked after an out-of-limits bio check fails, resulting in a deadlock.

Q: Which Ubuntu kernel packages are listed as affected?

The listed packages are ubuntu/linux-riscv, ubuntu/linux-realtime, ubuntu/linux-hwe-edge, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-azure-fde, ubuntu/linux-gke, and ubuntu/linux-aws-5.0.

Updated

In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix a bug if the bio is out of limits If dmintegritychecklimits fails, the code would exit with DMMAPIOKILL. However, the range would be already locked at this point, and it wouldn't be unlocked, resulting in a deadlock. Let's move the limit check up, so that when it exits, no resources are leaked.
