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()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/mpi3mr/mpi3mr_app.c"],"versions":[{"version":"f5e6d5a343761081317c89d23489c93fbafc69ff","lessThan":"8ba997b22f2cd5d29aad8c39f6201f7608ed0c04","status":"affected","versionType":"git"},{"version":"f5e6d5a343761081317c89d23489c93fbafc69ff","lessThan":"2f3d3fa5b8ed7d3b147478f42b00b468eeb1ecd2","status":"affected","versionType":"git"},{"version":"f5e6d5a343761081317c89d23489c93fbafc69ff","lessThan":"fb428a2005fc1260d18b989cc5199f281617f44d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/mpi3mr/mpi3mr_app.c"],"versions":[{"version":"5.19","status":"affected"},{"version":"0","lessThan":"5.19","status":"unaffected","versionType":"semver"},{"version":"6.1.16","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.2.3","lessThanOrEqual":"6.2.*","status":"unaffected","versionType":"semver"},{"version":"6.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.1.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.2.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/8ba997b22f2cd5d29aad8c39f6201f7608ed0c04"},{"url":"https://git.kernel.org/stable/c/2f3d3fa5b8ed7d3b147478f42b00b468eeb1ecd2"},{"url":"https://git.kernel.org/stable/c/fb428a2005fc1260d18b989cc5199f281617f44d"}],"title":"scsi: mpi3mr: Fix issues in mpi3mr_get_all_tgt_info()","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.8,"attackVector":"LOCAL","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"id":"CVE-2023-53320","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-01-14T18:27:12.112588Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-787","description":"CWE-787 Out-of-bounds Write"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-01-14T18:32:58.371Z"}}]}}
