Both amdgpu_ras_get_context() and\namdgpu_ras_find_obj() can return NULL, e.g. during the window between\nadev->nbio.ras being set (early in amdgpu_ras_init(), by design, to\nenable the fatal-error interrupt as soon as possible) and the PCIE_BIF\nras object actually being created in RAS late_init. Any interrupt in that\nwindow crashes in hard-IRQ context.\n\nThis is analogous to commit d190b459b2a4 (\"drm/amdgpu: the warning\ndereferencing obj for nbio_v7_4\"), which fixed the same issue in the\nnbio_v7_4 handler.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.\n\n(cherry picked from commit c7071767a50a32ed727cf800ac84372429e3b4b3)","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98270","source_modified_at":"2026-10-19T09:16:41.028Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"7692e1ee2446fd1940b5caa6e09779504a58881a","lessThan":"b7c7f07a40037514f8e890aa00f8d7b196d680cf","status":"affected","versionType":"git"},{"version":"7692e1ee2446fd1940b5caa6e09779504a58881a","lessThan":"fc5f845a291fc8175e6857cd6ad042818da192e8","status":"affected","versionType":"git"},{"version":"7692e1ee2446fd1940b5caa6e09779504a58881a","lessThan":"37583946d8751f8e285c467d770ac0b609b82a23","status":"affected","versionType":"git"},{"version":"7692e1ee2446fd1940b5caa6e09779504a58881a","lessThan":"315c22712715491f0dfafdaf2c2b437540e68702","status":"affected","versionType":"git"},{"version":"7692e1ee2446fd1940b5caa6e09779504a58881a","lessThan":"723d4dc628d764b19cf9efca14b82cca5ff020c9","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98270","source_modified_at":"2026-10-19T09:16:41.028Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.6","status":"affected"},{"version":"0","lessThan":"6.6","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98270","source_modified_at":"2026-10-19T09:16:41.028Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"37583946d8751f8e285c467d770ac0b609b82a23","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98270","source_modified_at":"2026-10-19T09:16:41.028Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"315c22712715491f0dfafdaf2c2b437540e68702","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98270","source_modified_at":"2026-10-19T09:16:41.028Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"723d4dc628d764b19cf9efca14b82cca5ff020c9","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00175,"percentile":0.06669,"score_date":"2026-10-23"},"published_at":"2026-10-06T08:45:32.506Z","modified_at":"2026-10-19T09:16:41.028Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98270","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:16:41.028Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98270","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/b7c7f07a40037514f8e890aa00f8d7b196d680cf"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/fc5f845a291fc8175e6857cd6ad042818da192e8"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/37583946d8751f8e285c467d770ac0b609b82a23"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/315c22712715491f0dfafdaf2c2b437540e68702"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/723d4dc628d764b19cf9efca14b82cca5ff020c9"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:16:41.028Z","content_hash":"eb2980c7c7cc0f259f5daa4c37a1ce5f9e72eb60ef387760d3cda723036d4dfe"}}
