Vulnerability from gsd
Modified
2024-02-21 06:01
Details
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]
