Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bus: mhi: host: Drop chan lock before queuing buffers<br /> <br /> Ensure read and write locks for the channel are not taken in succession by<br /> dropping the read lock from parse_xfer_event() such that a callback given<br /> to client can potentially queue buffers and acquire the write lock in that<br /> process. Any queueing of buffers should be done without channel read lock<br /> acquired as it can result in multiple locks and a soft lockup.<br /> <br /> [mani: added fixes tag and cc&amp;#39;ed stable]
