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

gve: fix XSK buffer leak on error descriptor

When the error bit is set in the RX completion descriptor, the buf_state
and its attached buffer should be freed. In the case of AF_XDP ZC, the
XSK buffer was not freed, leading to a leak.

This issue was caught by LLM.
