In x86 non-RT, DC_FP_START takes fpregs_lock(),\nwhich disables local softirqs.\n\nThe DML1 path through dcn32_enable_phantom_plane() calls kvzalloc() to\nallocate ~335 KiB for dc_plane_state. This triggers the vmalloc path,\nwhich calls BUG_ON(in_interrupt()) because it's invoked within the\nFPU-enabled (softirq disabled) region, leading to a kernel crash.\n\n[How]\nWrap the dc_state_create_phantom_plane() call with the\nDC_RUN_WITH_PREEMPTION_ENABLED() macro to allow preemption during\nthis memory allocation.\n\n(cherry picked from commit 885ccbef7b94a8b38f69c4211c679021aa27ad11)","published_at":"2026-06-26T19:40:46.328000Z","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/30bb2ec6695d62f63db4aa6179c4626834ed0cd6","https://git.kernel.org/stable/c/183182235f6d53bac62c6c39014738a54a68dfa6"],"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":"235c67634230b0f9ad8c0185272fed36c892b1c4","version_start_inclusive":true,"version_end":"30bb2ec6695d62f63db4aa6179c4626834ed0cd6","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:235c67634230b0f9ad8c0185272fed36c892b1c4:30bb2ec6695d62f63db4aa6179c4626834ed0cd6"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"235c67634230b0f9ad8c0185272fed36c892b1c4","version_start_inclusive":true,"version_end":"183182235f6d53bac62c6c39014738a54a68dfa6","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:235c67634230b0f9ad8c0185272fed36c892b1c4:183182235f6d53bac62c6c39014738a54a68dfa6"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.0","version_start_inclusive":true,"version_end":"6.0","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.0:6.0"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.0","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.0"},{"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/30bb2ec6695d62f63db4aa6179c4626834ed0cd6","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/183182235f6d53bac62c6c39014738a54a68dfa6","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-26T19:40:46.328000Z","label":"CVE published","source":null}]}
