Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The vulnerability is related to the
dp aux cmd fifo tx() function in the Linux kernel's DP component. It is caused by synchronization errors when using a shared resource, which can lead to a race condition. This may cause the aux read transaction to return prematurely, resulting in the host's receiving buffer containing unexpected data. The issue is fixed by checking the aux isr and returning immediately at the aux isr handler if there are no isr status bits set. A bug report regarding eDP EDID corruption during system boot-up has been resolved, which was caused by the VIDEO READY interrupt continuously firing and causing dp aux isr() to complete dp aux cmd fifo tx() prematurely.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
