no network or remote-peer data reaches this path.\nAC:H - Triggering requires a kernel memory-allocation failure at one of ~20 specific sites inside the probe, plus the non-default `qlini_mode=exclusive|disabled|dual` (FC target) or `ql2xsecenable=1` on QLA28xx — neither the timing of the probe nor which allocation fails is under the attacker's control.\nPR:L - The only attacker-supplied ingredient is memory exhaustion/fragmentation, which any unprivileged local user can create; the probe itself is driven by ordinary system activity (boot, PCI hotplug, udev/driver rebind), so no elevated privilege is needed for the attacker's half.\nUI:N - Once the allocation failure occurs during probe, the error unwind and the second `kfree()` in `qla2x00_mem_free()` happen automatically inside the kernel with no action by any other user.\nS:U - The corruption is confined to the kernel slab allocator on the same host and crosses no virtualization, IOMMU, or sandbox authority boundary.\nC:H - The double free of the 4 KB `vp_map` object lets the same slab object be handed to two owners, yielding a use-after-free read primitive over whatever kernel structure lands there — potentially arbitrary kernel memory disclosure.\nI:H - Freelist corruption from the double free gives overlapping allocations, the classic path to controlled kernel heap writes and control-flow hijack; the freed 4 KB object is also a prime heap-spray target.\nA:H - With `CONFIG_SLAB_FREELIST_HARDENED`/SLUB debug the second `kfree()` is detected and BUG()s immediately; without it, freelist corruption reliably leads to an oops or panic." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/scsi/qla2xxx/qla_os.c" ], "versions": [ { "version": "430eef03a763e5e76a371ba6d02779ae4a64b6ea", "lessThan": "f14cee7a882cb79528f17a2335f53e9fd1848467", "status": "affected", "versionType": "git" }, { "version": "430eef03a763e5e76a371ba6d02779ae4a64b6ea", "lessThan": "b7deb675d674f44e0ddbab87fee8f9f098925e73", "status": "affected", "versionType": "git" }, { "version": "430eef03a763e5e76a371ba6d02779ae4a64b6ea", "lessThan": "825d63164a2e6bacb059a9afb5605425b485413f", "status": "affected", "versionType": "git" }, { "version": "430eef03a763e5e76a371ba6d02779ae4a64b6ea", "lessThan": "e288285d47784fdcf7c81be56df7d65c6f10c58b", "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/qla2xxx/qla_os.c" ], "versions": [ { "version": "6.3", "status": "affected" }, { "version": "0", "lessThan": "6.3", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.24", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7.12", "lessThanOrEqual": "6.7.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.3", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9", "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": "6.3", "versionEndExcluding": "6.6.24" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.7.12" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.8.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.9" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/f14cee7a882cb79528f17a2335f53e9fd1848467" }, { "url": "https://git.kernel.org/stable/c/b7deb675d674f44e0ddbab87fee8f9f098925e73" }, { "url": "https://git.kernel.org/stable/c/825d63164a2e6bacb059a9afb5605425b485413f" }, { "url": "https://git.kernel.org/stable/c/e288285d47784fdcf7c81be56df7d65c6f10c58b" } ], "title": "scsi: qla2xxx: Fix double free of the ha->vp_map pointer", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2024-06-17T17:40:52.767633Z", "id": "CVE-2024-26930", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-06-17T17:46:59.086Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T00:21:05.520Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/f14cee7a882cb79528f17a2335f53e9fd1848467", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/b7deb675d674f44e0ddbab87fee8f9f098925e73", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/825d63164a2e6bacb059a9afb5605425b485413f", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/e288285d47784fdcf7c81be56df7d65c6f10c58b", "tags": [ "x_transferred" ] } ] } ] } }
