Summary
In the Linux kernel, the following vulnerability has been resolved:
net: wwan: iosm: Fix tainted pointer delete is case of region creation fail
In case of region creation fail in ipc_devlink_create_region(), previously
created regions delete process starts from tainted pointer which actually

Fix this bug by decreasing region index before delete.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
