CVE-2025-40192

In the Linux kernel, the following vulnerability has been resolved:

Revert "ipmi: fix msg stack when IPMI is disconnected"

This reverts commit c608966f3f9c2dca596967501d00753282b395fc.

This patch has a subtle bug that can cause the IPMI driver to go into an infinite loop if the BMC misbehaves in a certain way. Apparently certain BMCs do misbehave this way because several reports have come in recently about this.
