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.","published_at":"2026-06-26T19:40:47.210000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/722b91d5086a249318c9d0e2b36aeac80ba8c808","https://git.kernel.org/stable/c/f319de7074e1728a9f9ff7134257360c694ec2b2","https://git.kernel.org/stable/c/6c77b9510829a424d1b74409b7db9456e3522871"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:28.590503Z","updated_at":"2026-06-28T23:30:52.348775Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"f4312e6bfa2a98e94dacc75f96f916b76bdf4259","version_start_inclusive":true,"version_end":"722b91d5086a249318c9d0e2b36aeac80ba8c808","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:f4312e6bfa2a98e94dacc75f96f916b76bdf4259:722b91d5086a249318c9d0e2b36aeac80ba8c808"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"f4312e6bfa2a98e94dacc75f96f916b76bdf4259","version_start_inclusive":true,"version_end":"f319de7074e1728a9f9ff7134257360c694ec2b2","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:f4312e6bfa2a98e94dacc75f96f916b76bdf4259:f319de7074e1728a9f9ff7134257360c694ec2b2"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"f4312e6bfa2a98e94dacc75f96f916b76bdf4259","version_start_inclusive":true,"version_end":"6c77b9510829a424d1b74409b7db9456e3522871","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:f4312e6bfa2a98e94dacc75f96f916b76bdf4259:6c77b9510829a424d1b74409b7db9456e3522871"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.17","version_start_inclusive":true,"version_end":"6.17","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.17:6.17"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.17","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.17"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.18.33","version_start_inclusive":true,"version_end":"6.18.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.18.33:6.18.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.0.10","version_start_inclusive":true,"version_end":"7.0.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.0.10:7.0.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.1","version_start_inclusive":true,"version_end":"*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.1:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://git.kernel.org/stable/c/722b91d5086a249318c9d0e2b36aeac80ba8c808","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/f319de7074e1728a9f9ff7134257360c694ec2b2","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/6c77b9510829a424d1b74409b7db9456e3522871","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-26T19:40:47.210000Z","label":"CVE published","source":null}]}
