LIN1021-7602 : Security Advisory - linux - CVE-2023-52493

Created: Mar 2, 2024    Updated: Apr 9, 2024
Resolved Date: Apr 9, 2024
Found In Version:
Severity: Standard
Applicable for: Wind River Linux LTS 21
Component/s: Kernel


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.
