CVE-2022-50060

MEDIUM

Linux Kernel 5.0-5.15.63, 5.16.0-5.19.4, >=6.0 - Use-After-Free in octeontx2-af MCAM Entry Handling

Title source: llm

Description

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.
