UBUNTU-CVE-2025-40207: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: Who can exploit this issue?

The CVSS vector indicates that exploitation requires local access and high privileges. It also specifies that additional attack requirements are present, so this is not described as a straightforward low-privilege remote attack.

Q: What is the likely impact if exploitation succeeds?

The described failure can crash the kernel when subdevice-state allocation fails and the resulting error pointer is used. The CVSS impact is limited to availability, with no stated impact on confidentiality or integrity.

Q: Which Ubuntu kernel packages are identified as affected?

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

Updated

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-subdev: Fix alloc failure check in v4l2subdevcallstatetry() v4l2subdevcallstatetry() macro allocates a subdev state with v4l2subdevstatealloc(), but does not check the returned value. If v4l2subdevstatealloc fails, it returns an ERRPTR, and that would cause v4l2subdevcallstatetry() to crash. Add proper error handling to v4l2subdevcallstatetry().
