When the device\nreports a single receive queue, rndis_filter_device_add() does not\nallocate an indirection table, accepting RSS hash key updates in this\nstate leads to a hang.\n\nFix this by gating netvsc_set_rxfh() on ndc->rx_table_sz and return\n-EOPNOTSUPP when the table is absent. This aligns set_rxfh with the device\ncapabilities and prevents incorrect behavior."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/hyperv/netvsc_drv.c"],"versions":[{"version":"962f3fee83a4ef9010ae84dc43ae7aecb572e2a9","lessThan":"8288136f508e78eb3563e7073975999cf225a2f9","status":"affected","versionType":"git"},{"version":"962f3fee83a4ef9010ae84dc43ae7aecb572e2a9","lessThan":"82c9039c8ebb715753a40434df714f865a3aec9c","status":"affected","versionType":"git"},{"version":"962f3fee83a4ef9010ae84dc43ae7aecb572e2a9","lessThan":"4cd55c609e85ae2313248ef1a33619a3eef44a16","status":"affected","versionType":"git"},{"version":"962f3fee83a4ef9010ae84dc43ae7aecb572e2a9","lessThan":"11dd9a9ef4dc4507a15a69b8511a0013c6c28fa3","status":"affected","versionType":"git"},{"version":"962f3fee83a4ef9010ae84dc43ae7aecb572e2a9","lessThan":"d23564955811da493f34412d7de60fa268c8cb50","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/hyperv/netvsc_drv.c"],"versions":[{"version":"4.11","status":"affected"},{"version":"0","lessThan":"4.11","status":"unaffected","versionType":"semver"},{"version":"6.1.162","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.122","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.67","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.7","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.11","versionEndExcluding":"6.1.162"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.11","versionEndExcluding":"6.6.122"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.11","versionEndExcluding":"6.12.67"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.11","versionEndExcluding":"6.18.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.11","versionEndExcluding":"6.19"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/8288136f508e78eb3563e7073975999cf225a2f9"},{"url":"https://git.kernel.org/stable/c/82c9039c8ebb715753a40434df714f865a3aec9c"},{"url":"https://git.kernel.org/stable/c/4cd55c609e85ae2313248ef1a33619a3eef44a16"},{"url":"https://git.kernel.org/stable/c/11dd9a9ef4dc4507a15a69b8511a0013c6c28fa3"},{"url":"https://git.kernel.org/stable/c/d23564955811da493f34412d7de60fa268c8cb50"}],"title":"net: hv_netvsc: reject RSS hash key programming without RX indirection table","x_generator":{"engine":"bippy-1.2.0"}}}}
