CVE-2022-50060

Estado: AnalizadaMedia (5.5)—

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

octeontx2-af: Fix mcam entry resource leak

The teardown sequence in FLR handler returns if no NIX LF is attached to PF/VF because it indicates that graceful shutdown of resources already happened. But there is a chance of all allocated MCAM entries not being freed by PF/VF. Hence free mcam entries even in case of detached LF.
