UBUNTU-CVE-2024-49963: Medium severity ubuntu/linux-aws vulnerability

Q: Which systems are realistically exposed to this issue?

The issue affects systems using the BCM2835 mailbox and Raspberry Pi firmware power driver during suspend and resume. The provided software list includes Ubuntu kernel packages for FIPS, AWS, Azure, GCP, and Oracle variants, but the described hardware path is specifically Raspberry Pi/BCM2835-related.

Q: What conditions are required to trigger the problem?

The system must enter the noirq suspend phase while the Raspberry Pi power driver performs a firmware property transaction. With the mailbox IRQ disabled during suspend, rpi_firmware_property_list() can time out.

Q: What is the operational impact?

Affected systems can log firmware transaction timeout warnings during suspend, because the firmware property request cannot complete while the mailbox IRQ is disabled. The reported impact is availability-related rather than confidentiality or integrity-related.

Q: How can I tell whether a system is affected?

Check suspend/resume logs for warnings from rpi_firmware_property_list() containing "Firmware transaction 0x00028001 timeout." The supplied example occurs during late device suspend and includes a call path through rpi_firmware_set_power().

Updated

In the Linux kernel, the following vulnerability has been resolved: mailbox: bcm2835: Fix timeout during suspend mode During noirq suspend phase the Raspberry Pi power driver suffer of firmware property timeouts. The reason is that the IRQ of the underlying BCM2835 mailbox is disabled and rpifirmwarepropertylist() will always run into a timeout [1]. Since the VideoCore side isn't consider as a wakeup source, set the IRQFNOSUSPEND flag for the mailbox IRQ in order to keep it enabled during suspend-resume cycle.

DescriptionSeverityAffected Software

Frequently Asked Questions

Which systems are realistically exposed to this issue?

The issue affects systems using the BCM2835 mailbox and Raspberry Pi firmware power driver during suspend and resume. The provided software list includes Ubuntu kernel packages for FIPS, AWS, Azure, GCP, and Oracle variants, but the described hardware path is specifically Raspberry Pi/BCM2835-related.

What conditions are required to trigger the problem?

The system must enter the noirq suspend phase while the Raspberry Pi power driver performs a firmware property transaction. With the mailbox IRQ disabled during suspend, rpi_firmware_property_list() can time out.

What is the operational impact?

Affected systems can log firmware transaction timeout warnings during suspend, because the firmware property request cannot complete while the mailbox IRQ is disabled. The reported impact is availability-related rather than confidentiality or integrity-related.

How can I tell whether a system is affected?

Check suspend/resume logs for warnings from rpi_firmware_property_list() containing "Firmware transaction 0x00028001 timeout." The supplied example occurs during late device suspend and includes a call path through rpi_firmware_set_power().
