Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.
