A pool failure jumps to out_free_buffer_pools without\nh_free_logical_lan(), so PHYP still owns the buffer-list page when\nit is unmapped. request_irq() failure already issued the hypercall\nbefore taking the same label.\n\nMove that h_free to the shared post-register unwind so both paths\nderegister before the buffer list is unmapped.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99045","source_modified_at":"2026-10-23T12:22:09.352Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"d43732ce021f4244a4c53a45d57ad0c13c30ed94","lessThan":"decb4d4ead2c71ef698727734ab5024a872eb372","status":"affected","versionType":"git"},{"version":"d43732ce021f4244a4c53a45d57ad0c13c30ed94","lessThan":"c54bbdf6f0731102a4bf7f5e4ee535b3ea415996","status":"affected","versionType":"git"},{"version":"d43732ce021f4244a4c53a45d57ad0c13c30ed94","lessThan":"a065bd31ec462f6f9c267026b708dd020f122723","status":"affected","versionType":"git"},{"version":"d43732ce021f4244a4c53a45d57ad0c13c30ed94","lessThan":"d24fdec1413c656d29298097926e77542785ca0c","status":"affected","versionType":"git"},{"version":"d43732ce021f4244a4c53a45d57ad0c13c30ed94","lessThan":"af0524bf4ce1a4cbd2946aa81751582951cfcab5","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99045","source_modified_at":"2026-10-23T12:22:09.352Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"4.13","status":"affected"},{"version":"0","lessThan":"4.13","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.57","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.11","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T12:22:09.352Z","modified_at":"2026-10-23T12:22:09.352Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99045","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:22:09.352Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/decb4d4ead2c71ef698727734ab5024a872eb372"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c54bbdf6f0731102a4bf7f5e4ee535b3ea415996"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/a065bd31ec462f6f9c267026b708dd020f122723"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d24fdec1413c656d29298097926e77542785ca0c"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/af0524bf4ce1a4cbd2946aa81751582951cfcab5"}],"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":"2026-10-23T12:22:09.352Z","content_hash":"f65747174a7ffdd5925fcfad0b60898c162155ba3fbf637d11134ee149d15a8c"}}
