Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the Linux kernel's mhi component, where a vulnerability has been resolved by dropping the channel lock before queuing buffers. This ensures that read and write locks for the channel are not taken in succession, which could result in multiple locks and a soft lockup. The vulnerability can be exploited to cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
