The\nuninit call will trigger put_device(), which invokes the release\ncallback (idpf_vport_adev_release / idpf_core_adev_release) that frees\niadev.  The fall-through then reads adev->id from the freed iadev for\nida_free() and double-frees iadev with kfree().\n\nFree the IDA slot and clear the back-pointer before uninit, while adev\nis still valid, then return immediately.\n\nCommit 65637c3a1811 (\"idpf: fix UAF in RDMA core aux dev deinitialization\")\nfixed the same use-after-free in the matching unplug path in this file but\nmissed both probe error paths."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/intel/idpf/idpf_idc.c"],"versions":[{"version":"f4312e6bfa2a98e94dacc75f96f916b76bdf4259","lessThan":"722b91d5086a249318c9d0e2b36aeac80ba8c808","status":"affected","versionType":"git"},{"version":"f4312e6bfa2a98e94dacc75f96f916b76bdf4259","lessThan":"f319de7074e1728a9f9ff7134257360c694ec2b2","status":"affected","versionType":"git"},{"version":"f4312e6bfa2a98e94dacc75f96f916b76bdf4259","lessThan":"6c77b9510829a424d1b74409b7db9456e3522871","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/ethernet/intel/idpf/idpf_idc.c"],"versions":[{"version":"6.17","status":"affected"},{"version":"0","lessThan":"6.17","status":"unaffected","versionType":"semver"},{"version":"6.18.33","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.10","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"6.17","versionEndExcluding":"6.18.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"7.0.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/722b91d5086a249318c9d0e2b36aeac80ba8c808"},{"url":"https://git.kernel.org/stable/c/f319de7074e1728a9f9ff7134257360c694ec2b2"},{"url":"https://git.kernel.org/stable/c/6c77b9510829a424d1b74409b7db9456e3522871"}],"title":"idpf: fix double free and use-after-free in aux device error paths","x_generator":{"engine":"bippy-1.2.0"}}}}
