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