The\n correct size is sizeof(u64).\n\n2) When it calculates the valid entry length kern_entrylen, it excludes one\n entry by subtracting 1 from num_devices.\n\n3) It copies num_device by calling memcpy(). Substitution is enough.\n\n4) It does not specify the calculated length to sg_copy_from_buffer().\n Instead, it specifies the payload length which is larger than the\n alltgt_info size. It causes \"BUG: KASAN: slab-out-of-bounds\".\n\nFix the issues by using the correct header size, removing the subtraction\nfrom num_devices, replacing the memcpy() with substitution and specifying\nthe correct length to sg_copy_from_buffer()."}], "lastModified": "2026-01-14T19:16:25.747", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A9E5492C-0786-4BD9-A043-DBAA6E28BFE6", "versionEndExcluding": "6.1.16", "versionStartIncluding": "5.19"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "88C67289-22AD-4CA9-B202-5F5A80E5BA4B", "versionEndExcluding": "6.2.3", "versionStartIncluding": "6.2"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
