Title
scsi: qla2xxx: Fix double free of the ha->vp_map pointer
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix double free of the ha->vp_map pointer
Coverity scan reported potential risk of double free of the pointer
ha->vp_map. ha->vp_map was freed in qla2x00_mem_alloc(), and again freed
in function qla2x00_mem_free(ha).
Assign NULL to vp_map and kfree take care of NULL.

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 \\u2014 neither the timing of the probe nor which allocation fails is under the attacker\u0027s 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\u0027s 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 \\u2014 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\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"430eef03a763e5e76a371ba6d02779ae4a64b6ea\", \"lessThan\": \"f14cee7a882cb79528f17a2335f53e9fd1848467\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"430eef03a763e5e76a371ba6d02779ae4a64b6ea\", \"lessThan\": \"b7deb675d674f44e0ddbab87fee8f9f098925e73\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"430eef03a763e5e76a371ba6d02779ae4a64b6ea\", \"lessThan\": \"825d63164a2e6bacb059a9afb5605425b485413f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"430eef03a763e5e76a371ba6d02779ae4a64b6ea\", \"lessThan\": \"e288285d47784fdcf7c81be56df7d65c6f10c58b\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/scsi/qla2xxx/qla_os.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.3\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.3\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.24\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.3\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/scsi/qla2xxx/qla_os.c\"], \"defaultStatus\": \"affected\"}], \"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\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nscsi: qla2xxx: Fix double free of the ha-\u003evp_map pointer\\n\\nCoverity scan reported potential risk of double free of the pointer\\nha-\u003evp_map. ha-\u003evp_map was freed in qla2x00_mem_alloc(), and again freed\\nin function qla2x00_mem_free(ha).\\n\\nAssign NULL to vp_map and kfree take care of NULL.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.24\", \"versionStartIncluding\": \"6.3\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.7.12\", \"versionStartIncluding\": \"6.3\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.8.3\", \"versionStartIncluding\": \"6.3\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.9\", \"versionStartIncluding\": \"6.3\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T11:28:25.607Z\"}}}",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
