But if there is no next packet and the interface is\nbrought down instead, ice_clean_tx_ring() -> ice_unmap_and_free_tx_buf()\nwill find the tx_buf and free the skb for the second time.\n\nThe fix is to reset the tx_buf type to ICE_TX_BUF_EMPTY in the error\npath, so that ice_unmap_and_free_tx_buf().\nMove the initialization of 'first' up, to ensure it's already valid in\ncase we hit the linearization error path.\n\nThe bug was spotted by AI while I had it looking for something else.\nIt also proposed an initial version of the patch.\n\nI reproduced the bug and tested the fix by adding code to inject\nfailures, on a build with KASAN.\n\nI looked for similar bugs in related Intel drivers and did not find any.","published_at":"2026-06-24T16:29:20.332000Z","last_modified_at":null,"cvss_v3_score":7.8,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","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/4c08fc2119ef0281cfa2cee007acf0a251be55f2","https://git.kernel.org/stable/c/1a303baa715e6b78d6a406aaf335f87ff35acfcd"],"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":"2026-06-28T17:55:22.518073Z","updated_at":"2026-06-28T23:30:49.890169Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"d76a60ba7afb89523c88cf2ed3a044ce4180289e","version_start_inclusive":true,"version_end":"4c08fc2119ef0281cfa2cee007acf0a251be55f2","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:d76a60ba7afb89523c88cf2ed3a044ce4180289e:4c08fc2119ef0281cfa2cee007acf0a251be55f2"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"d76a60ba7afb89523c88cf2ed3a044ce4180289e","version_start_inclusive":true,"version_end":"1a303baa715e6b78d6a406aaf335f87ff35acfcd","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:d76a60ba7afb89523c88cf2ed3a044ce4180289e:1a303baa715e6b78d6a406aaf335f87ff35acfcd"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"4.17","version_start_inclusive":true,"version_end":"4.17","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:4.17:4.17"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"4.17","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:4.17"},{"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/4c08fc2119ef0281cfa2cee007acf0a251be55f2","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/1a303baa715e6b78d6a406aaf335f87ff35acfcd","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-24T16:29:20.332000Z","label":"CVE published","source":null}]}
