| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue arises due to a mutex being called inside a spinlock in the tegra i2c module on ACPI machines. This leads to a bug where a sleeping function is called from an invalid context, resulting in an error. The problem occurs because the spinlock
&dev->power.lock is acquired before rpm resume() is called, and later rpm resume() invokes acpi subsys runtime resume(), which relies on mutexes, triggering the error. To address this issue, devices on ACPI are now marked as not IRQ-safe, considering the dependency of acpi subsys runtime resume() on mutexes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
