{"schema":"threatline.record/2","record":{"id":"CVE-2026-98386","aliases":[],"summary":"scsi: qla2xxx: Use memset_io() to clear QLAFX00 request ring slot","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Use memset_io() to clear QLAFX00 request ring slot\n\nFor QLAFX00 the request ring is ioremapped device I/O memory\n(ha->iobase + req_que_off), not DMA-coherent RAM, which is why the rest\nof the FX00 path accesses it through memcpy_toio() and the wrt_reg_*\nhelpers. __qla2x00_alloc_iocbs() however zeroed the producer slot with a\nplain memset(). On architectures such as ARM64 a regular memset() may\nemit unaligned or block-zeroing instructions (e.g. DC ZVA) that are\ninvalid on Device memory, leading to a synchronous external abort.\n\nUse memset_io() to clear the slot for QLAFX00, matching the I/O\naccessors used elsewhere on this ring. Other adapters keep the plain\nmemset() on their DMA-coherent rings. The zero-fill is retained for FX00\nbecause its IOCB builders (e.g. qlafx00_fxdisc_iocb()) copy only part of\nthe entry and rely on the unused tail being pre-zeroed.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98386","source_modified_at":"2026-10-21T12:55:01.405Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"2df8c8630904794100189fa3d70598642e1877ce","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"53eb96c244d150dfb8cc4b5b0492ab53755f3701","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"6ee6dfd922fafd508f6bde16de30dd2db796b7a7","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"e41d28d9a242c4005b7d01a7ee7769405a6a2c2e","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"626e44f3d8a924a97a3848a9fd45833947e081e9","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98386","source_modified_at":"2026-10-21T12:55:01.405Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"3.10","status":"affected"},{"version":"0","lessThan":"3.10","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","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-2026-98386","source_modified_at":"2026-10-21T12:55:01.405Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"2df8c8630904794100189fa3d70598642e1877ce","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98386","source_modified_at":"2026-10-21T12:55:01.405Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"53eb96c244d150dfb8cc4b5b0492ab53755f3701","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98386","source_modified_at":"2026-10-21T12:55:01.405Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6ee6dfd922fafd508f6bde16de30dd2db796b7a7","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98386","source_modified_at":"2026-10-21T12:55:01.405Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"626e44f3d8a924a97a3848a9fd45833947e081e9","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00209,"percentile":0.10535,"score_date":"2026-10-23"},"published_at":"2026-10-14T13:25:50.908Z","modified_at":"2026-10-21T12:55:01.405Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98386","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:55:01.405Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98386","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/2df8c8630904794100189fa3d70598642e1877ce"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/53eb96c244d150dfb8cc4b5b0492ab53755f3701"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/6ee6dfd922fafd508f6bde16de30dd2db796b7a7"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e41d28d9a242c4005b7d01a7ee7769405a6a2c2e"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/626e44f3d8a924a97a3848a9fd45833947e081e9"}],"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":"2026-10-21T12:55:01.405Z","content_hash":"436c4ec74f4f924d9586f5daa0380e52ec1912d0aad5b87942cb4a5f16a72d60"}}
