CVE-2025-39718 (GCVE-0-2025-39718)
Vulnerability from cvelistv5
Published
2025-09-05 17:21
Modified
2026-10-15 22:02
Severity ?
8.4 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Validate length in packet header before skb_put() When receiving a vsock packet in the guest, only the virtqueue buffer size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately, virtio_vsock_skb_rx_put() uses the length from the packet header as the length argument to skb_put(), potentially resulting in SKB overflow if the host has gone wonky. Validate the length as advertised by the packet header before calling virtio_vsock_skb_rx_put().

This matches the kernel CNA convention of AV:L for malicious-virtio-backend attacks on guest drivers.\nAC:L - The backend simply writes an arbitrary 32-bit value into the packet header\u0027s len field; no race, no memory-layout dependency, and the wraparound window that defeats skb_over_panic() is a fixed, deterministic 44-value range. Every trigger condition is fully under the attacker\u0027s control.\nPR:N - No privileges exist in the vulnerable component \u2014 the guest kernel \u2014 for the attacker to hold; virtio_transport_rx_work() consumes the buffer from a workqueue as soon as the device completes it, with no guest socket, user, or capability involved. Userspace VMMs (Firecracker, crosvm, vhost-user-vsock) are deliberately deprivileged, and under SEV-SNP/TDX/CCA the host is untrusted by design.\nUI:N - The RX work item processes the malicious buffer automatically on device completion, and the vsockmon tap path runs before any socket lookup. No guest user opens a socket, reads data, or performs any action.\nS:U - The vulnerable component and every impacted resource are the guest kernel and its own userspace, which share one security authority. Consistent with the S:U precedent for device\u2192guest virtio driver bugs (CVE-2026-46123, CVE-2026-64456, CVE-2026-64490); S:C in this subsystem has been reserved for guest\u2192host direction.\nC:H - A header len exceeding the bytes the device actually wrote makes skb_put() expose uninitialized kmalloc-8k slab contents, which recvmsg() copies straight to guest userspace, and the u32-wrap case leaves skb-\u003elen at ~4 GiB so skb_copy_datagram_iter() reads essentially unbounded guest kernel memory. Repeatable per packet with heap grooming, this is an arbitrary kernel-memory read.\nI:H - The wraparound bypasses skb_over_panic() and leaves a corrupted skb whose len/tail are desynchronized from the allocation; virtio_transport_build_skb() then truncates the size_t allocation size to 75 bytes and performs skb_put_data() of 0xFFFFFFFF, an unbounded out-of-bounds memcpy write out of a small slab object. Combined with the read primitive this is a heap-corruption primitive suitable for control-flow hijack in the guest.\nA:H - Any header len outside the narrow wrap window drives skb-\u003etail past skb-\u003eend, hitting skb_over_panic() \u2192 BUG() in the virtio_vsock workqueue, and the wrap path instead faults on a multi-gigabyte copy. Either way the guest kernel oopses or panics, triggerable at will and repeatedly."

This matches the kernel CNA convention of AV:L for malicious-virtio-backend attacks on guest drivers.\\nAC:L - The backend simply writes an arbitrary 32-bit value into the packet header\u0027s len field; no race, no memory-layout dependency, and the wraparound window that defeats skb_over_panic() is a fixed, deterministic 44-value range. Every trigger condition is fully under the attacker\u0027s control.\\nPR:N - No privileges exist in the vulnerable component \\u2014 the guest kernel \\u2014 for the attacker to hold; virtio_transport_rx_work() consumes the buffer from a workqueue as soon as the device completes it, with no guest socket, user, or capability involved. Userspace VMMs (Firecracker, crosvm, vhost-user-vsock) are deliberately deprivileged, and under SEV-SNP/TDX/CCA the host is untrusted by design.\\nUI:N - The RX work item processes the malicious buffer automatically on device completion, and the vsockmon tap path runs before any socket lookup. No guest user opens a socket, reads data, or performs any action.\\nS:U - The vulnerable component and every impacted resource are the guest kernel and its own userspace, which share one security authority. Consistent with the S:U precedent for device\\u2192guest virtio driver bugs (CVE-2026-46123, CVE-2026-64456, CVE-2026-64490); S:C in this subsystem has been reserved for guest\\u2192host direction.\\nC:H - A header len exceeding the bytes the device actually wrote makes skb_put() expose uninitialized kmalloc-8k slab contents, which recvmsg() copies straight to guest userspace, and the u32-wrap case leaves skb-\u003elen at ~4 GiB so skb_copy_datagram_iter() reads essentially unbounded guest kernel memory. Repeatable per packet with heap grooming, this is an arbitrary kernel-memory read.\\nI:H - The wraparound bypasses skb_over_panic() and leaves a corrupted skb whose len/tail are desynchronized from the allocation; virtio_transport_build_skb() then truncates the size_t allocation size to 75 bytes and performs skb_put_data() of 0xFFFFFFFF, an unbounded out-of-bounds memcpy write out of a small slab object. Combined with the read primitive this is a heap-corruption primitive suitable for control-flow hijack in the guest.\\nA:H - Any header len outside the narrow wrap window drives skb-\u003etail past skb-\u003eend, hitting skb_over_panic() \\u2192 BUG() in the virtio_vsock workqueue, and the wrap path instead faults on a multi-gigabyte copy. Either way the guest kernel oopses or panics, triggerable at will and repeatedly.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"baddcc2c71572968cdaeee1c4ab3dc0ad90fa765\", \"lessThan\": \"969b06bd8b7560efb100a34227619e7d318fbe05\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"71dc9ec9ac7d3eee785cdc986c3daeb821381e20\", \"lessThan\": \"ee438c492b2e0705d819ac0e25d04fae758d8f8f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"71dc9ec9ac7d3eee785cdc986c3daeb821381e20\", \"lessThan\": \"faf332a10372390ce65d0b803888f4b25a388335\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"71dc9ec9ac7d3eee785cdc986c3daeb821381e20\", \"lessThan\": \"676f03760ca1d69c2470cef36c44dc152494b47c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"71dc9ec9ac7d3eee785cdc986c3daeb821381e20\", \"lessThan\": \"0dab92484474587b82e8e0455839eaf5ac7bf894\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"6.1.63\", \"lessThan\": \"6.1.149\", \"versionType\": \"semver\"}], \"programFiles\": [\"net/vmw_vsock/virtio_transport.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\": \"6.1.149\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.103\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.44\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.16.4\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.16.*\"}, {\"status\": \"unaffected\", \"version\": \"6.17\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/vmw_vsock/virtio_transport.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/969b06bd8b7560efb100a34227619e7d318fbe05\"}, {\"url\": \"https://git.kernel.org/stable/c/ee438c492b2e0705d819ac0e25d04fae758d8f8f\"}, {\"url\": \"https://git.kernel.org/stable/c/faf332a10372390ce65d0b803888f4b25a388335\"}, {\"url\": \"https://git.kernel.org/stable/c/676f03760ca1d69c2470cef36c44dc152494b47c\"}, {\"url\": \"https://git.kernel.org/stable/c/0dab92484474587b82e8e0455839eaf5ac7bf894\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nvsock/virtio: Validate length in packet header before skb_put()\\n\\nWhen receiving a vsock packet in the guest, only the virtqueue buffer\\nsize is validated prior to virtio_vsock_skb_rx_put().
