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.","score":null,"severity":"unknown","published":"2026-10-14T13:25:50.908Z","modified":"2026-10-30T12:38:06.821Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"0eca1d7a4dac793224e6e295e29e00245e96cf16","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"337026cf8149dcfedacd60d6d7081bff10ee5cd4","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"6e8f1144d06cfd8cf8c346066efd8f572b28f768","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"2df8c8630904794100189fa3d70598642e1877ce","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"53eb96c244d150dfb8cc4b5b0492ab53755f3701","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"6ee6dfd922fafd508f6bde16de30dd2db796b7a7","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"e41d28d9a242c4005b7d01a7ee7769405a6a2c2e","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","status":"affected","lessThan":"626e44f3d8a924a97a3848a9fd45833947e081e9","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98386"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"3.10","status":"affected"},{"version":"0","status":"unaffected","lessThan":"3.10","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.112","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.53","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.7","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98386"}],"remediation":[],"references":["https://git.kernel.org/stable/c/0eca1d7a4dac793224e6e295e29e00245e96cf16","https://git.kernel.org/stable/c/337026cf8149dcfedacd60d6d7081bff10ee5cd4","https://git.kernel.org/stable/c/6e8f1144d06cfd8cf8c346066efd8f572b28f768","https://git.kernel.org/stable/c/2df8c8630904794100189fa3d70598642e1877ce","https://git.kernel.org/stable/c/53eb96c244d150dfb8cc4b5b0492ab53755f3701","https://git.kernel.org/stable/c/6ee6dfd922fafd508f6bde16de30dd2db796b7a7","https://git.kernel.org/stable/c/e41d28d9a242c4005b7d01a7ee7769405a6a2c2e","https://git.kernel.org/stable/c/626e44f3d8a924a97a3848a9fd45833947e081e9"],"sources":[{"name":"CVE","id":"CVE-2026-98386","modified":"2026-10-30T12:38:06.821Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98386"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:01:19.308Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T22:50:32.984Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
