UBUNTU-CVE-2025-38005: High severity ubuntu/linux-hwe-edge vulnerability

Q: Which systems are realistically exposed?

Exposure is limited to Ubuntu systems using an affected listed kernel package and the TI K3 UDMA DMA-engine driver. The reported diagnostic occurred on an ARM64 system.

Q: What level of access would an attacker need?

The severity vector indicates local access, low privileges, no user interaction, and high attack complexity with additional attack preconditions. It does not indicate a network-reachable attack path.

Q: How can administrators identify signs of this issue?

Systems with lock validation enabled may log a missing-lock warning involving k3-udma.c, udma_start, and the udma_check_tx_completion workqueue. The supplied example shows the warning emitted from virt-dma.h during UDMA transaction completion handling.

Frequently Asked Questions

Which systems are realistically exposed?

Exposure is limited to Ubuntu systems using an affected listed kernel package and the TI K3 UDMA DMA-engine driver. The reported diagnostic occurred on an ARM64 system.

What level of access would an attacker need?

The severity vector indicates local access, low privileges, no user interaction, and high attack complexity with additional attack preconditions. It does not indicate a network-reachable attack path.

How can administrators identify signs of this issue?

Systems with lock validation enabled may log a missing-lock warning involving k3-udma.c, udma_start, and the udma_check_tx_completion workqueue. The supplied example shows the warning emitted from virt-dma.h during UDMA transaction completion handling.
