CWE ID 401

Summary

CVE-2022-49583 is a vulnerability in the Linux kernel's ivf driver. This issue involved improper handling of dummy receive descriptors, leading to a memory leak. Previously, iavf failed to free the page allocated for the previous receive buffer when encountering a hardware-written dummy descriptor. Consequently, this unlikely event could result in a memory leak. The issue has been resolved by updating iavf_get_rx_buffer to return the rx_buffer value for dummy receive descriptors, ensuring proper memory management.
