Tobias noticed that this leads to\nrandom values being returned as the xdp_md->rx_queue_index value for XDP\nprograms running in a cpumap.\n\nThis means we're basically returning the contents of the uninitialised\nmemory, which is bad. Fix this by zero-initialising the rxq data\nstructure before running the XDP program." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
