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.

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.
Statement: A resource leak was identified in the FLR (Function Level Reset) handler of the OcteonTX2 AF driver, where MCAM entries could remain allocated even after a function teardown, particularly when the NIX LF was already detached. This patch ensures that MCAM entries are explicitly freed to prevent memory exhaustion or hardware resource leakag
