UBUNTU-CVE-2025-68804: Low severity ubuntu/linux-hwe-edge vulnerability

Q: What condition triggers the crash?

The use-after-free occurs after the cros_ec_ishtp driver is unbound while the cros_ec_console_log_work kernel thread continues to access the device.

Q: What is the relevant mitigation if the fixed kernel is not yet available?

Avoid unbinding the affected cros_ec_ishtp driver, since the reported use-after-free and crash occur after driver unbinding.

Q: Which Ubuntu kernel packages are listed as affected?

The listed packages are linux, linux-azure, linux-gcp, linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, and linux-realtime.

Updated

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: crosecishtp: Fix UAF after unbinding driver After unbinding the driver, another kthread crosecconsolelogwork is still accessing the device, resulting an UAF and crash. The driver doesn't unregister the EC device in .remove() which should shutdown sub-devices synchronously. Fix it.

Frequently Asked Questions

What condition triggers the crash?

The use-after-free occurs after the cros_ec_ishtp driver is unbound while the cros_ec_console_log_work kernel thread continues to access the device.

What is the relevant mitigation if the fixed kernel is not yet available?

Avoid unbinding the affected cros_ec_ishtp driver, since the reported use-after-free and crash occur after driver unbinding.

Which Ubuntu kernel packages are listed as affected?

The listed packages are linux, linux-azure, linux-gcp, linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, and linux-realtime.
