Put that *back* in the non-kjump path, to prevent purgatory from\ncrashing when trying to access it.","published_at":"2026-06-26T19:40:43.754000Z","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/b0bd7a850e1f082560959707dbf57b0402071646","https://git.kernel.org/stable/c/7dba9631faa2ee0785e8c2bf0e3d90a05f26dd8c","https://git.kernel.org/stable/c/786a45757dcdf8f2beb9d4a6db605db16c18b2b4"],"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":"2026-06-28T23:30:51.545322Z"},"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":"2cacf7f23a024ab1fdc603ca6a4f4c8b2de9f64e","version_start_inclusive":true,"version_end":"b0bd7a850e1f082560959707dbf57b0402071646","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2cacf7f23a024ab1fdc603ca6a4f4c8b2de9f64e:b0bd7a850e1f082560959707dbf57b0402071646"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2cacf7f23a024ab1fdc603ca6a4f4c8b2de9f64e","version_start_inclusive":true,"version_end":"7dba9631faa2ee0785e8c2bf0e3d90a05f26dd8c","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2cacf7f23a024ab1fdc603ca6a4f4c8b2de9f64e:7dba9631faa2ee0785e8c2bf0e3d90a05f26dd8c"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2cacf7f23a024ab1fdc603ca6a4f4c8b2de9f64e","version_start_inclusive":true,"version_end":"786a45757dcdf8f2beb9d4a6db605db16c18b2b4","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:2cacf7f23a024ab1fdc603ca6a4f4c8b2de9f64e:786a45757dcdf8f2beb9d4a6db605db16c18b2b4"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.14","version_start_inclusive":true,"version_end":"6.14","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.14:6.14"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.14","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.14"},{"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/b0bd7a850e1f082560959707dbf57b0402071646","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/7dba9631faa2ee0785e8c2bf0e3d90a05f26dd8c","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/786a45757dcdf8f2beb9d4a6db605db16c18b2b4","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-26T19:40:43.754000Z","label":"CVE published","source":null}]}
