Vulnerability from cvelistv5
Published
2026-07-19 14:56
Modified
2026-10-19 20:18
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: ethtool: coalesce: cap profile updates at NET_DIM_PARAMS_NUM_PROFILES ethnl_update_profile() walks the ETHTOOL_A_PROFILE_IRQ_MODERATION nest list with an index 'i' and writes new_profile[i++] without bounding i. The destination is kmemdup()'d at NET_DIM_PARAMS_NUM_PROFILES entries (5), but the Netlink nest count is entirely user-controlled. Netlink policies do not have support for constraining the number of nested entries (or number of multi-attr entries).

this capability is obtainable by an unprivileged user via user namespaces (unshare -Urn) or containers granted NET_ADMIN (e.g., hostNetwork pods).\\nUI:N - Exploitation requires only the attacker\u0027s own ethtool netlink SET_COALESCE request with a malformed profile nest; no action by another user or victim is needed.\\nS:U - The vulnerability corrupts kernel heap memory within the same kernel security domain; it does not by itself cross a VM, container, or IOMMU boundary to affect a separate security authority.\\nC:H - The out-of-bounds writes past the 120-byte (5 \\u00d7 24-byte dim_cq_moder) kmalloc allocation can corrupt adjacent slab objects, providing a standard heap-corruption primitive that can be leveraged for arbitrary kernel memory disclosure.\\nI:H - The attacker fully controls the overflowed u16 profile fields (usec, pkts, comps) written beyond the allocation boundary, enabling heap metadata or adjacent-object corruption that can be developed into arbitrary kernel write or code execution.\\nA:H - Heap corruption from unbounded profile indexing can cause immediate kernel oops/panic during the write or when the corrupted profile is subsequently used by DIM/virtio-net interrupt moderation paths.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"f750dfe825b904164688adeb147950e0e0c4d262\", \"lessThan\": \"d4c9cc7c47781c6f4fa29d80a1193a8bcd1525bc\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f750dfe825b904164688adeb147950e0e0c4d262\", \"lessThan\": \"0c02c190bcd9822477038ff2cee10ea584ac1b1d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f750dfe825b904164688adeb147950e0e0c4d262\", \"lessThan\": \"6205f7166d2dd14a017a5802c81e5bd1421a8635\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"f750dfe825b904164688adeb147950e0e0c4d262\", \"lessThan\": \"7281b096b072f6c6e30420e3467d738f2e4c4b57\", \"versionType\": \"git\"}], \"programFiles\": [\"net/ethtool/coalesce.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.11\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.11\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.12.93\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.35\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.0.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.0.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/ethtool/coalesce.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/d4c9cc7c47781c6f4fa29d80a1193a8bcd1525bc\"}, {\"url\": \"https://git.kernel.org/stable/c/0c02c190bcd9822477038ff2cee10ea584ac1b1d\"}, {\"url\": \"https://git.kernel.org/stable/c/6205f7166d2dd14a017a5802c81e5bd1421a8635\"}, {\"url\": \"https://git.kernel.org/stable/c/7281b096b072f6c6e30420e3467d738f2e4c4b57\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nethtool: coalesce: cap profile updates at NET_DIM_PARAMS_NUM_PROFILES\\n\\nethnl_update_profile() walks the ETHTOOL_A_PROFILE_IRQ_MODERATION\\nnest list with an index \u0027i\u0027 and writes new_profile[i++] without\\nbounding i.
