Linux kernel versions prior to 5.10.46+
Description:
The issue is related to a wrong list del operation in the smc lgr cleanup early function, which can cause memory corruption. This may lead to a list corruption panic. The vulnerability is due to the deletion of the list head instead of the link group from the link group list.

To resolve the issue, update the Linux kernel to a version later than 5.10.46+.
As a temporary workaround, consider disabling the smc lgr cleanup early function until a patch is available.
