Title
Revert "ipmi: fix msg stack when IPMI is disconnected"
Summary
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.
Severity
No CVSS data available.
