Details

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

ibmvnic: Free rwi on reset success

Free the rwi structure in the event that the last rwi in the list processed successfully. The logic in commit 4f408e1fa6e1 ("ibmvnic: retry reset if there are no other resets") introduces an issue that results in a 32 byte memory leak whenever the last rwi in the list gets processed.
