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: HID: bpf: Fix hid_bpf_get_data() range check hid_bpf_get_data() returns a pointer into the HID-BPF context data when the caller-provided offset and size fit inside ctx->allocated_size. The current check adds rdwr_buf_size and offset before comparing the result against ctx->allocated_size. Since both values are unsigned, a very large size can wrap the sum below ctx->allocated_size and make the helper return a pointer even though the requested range is not contained in the backing buffer. Use check_add_overflow() to reject wrapped range ends before comparing the requested range end against ctx->allocated_size.

per kernel CNA guidance this is Low because CAP_BPF can be delegated via BPF tokens into user namespaces, not only init-namespace root.\\nUI:N - The attacker loads and attaches their own HID-BPF program and triggers hid_bpf_get_data() from its callbacks; no separate victim action such as mounting, opening a file, or plugging in a device is required beyond the attacker\u0027s own bpf operations.\\nS:U - Exploitation corrupts kernel heap memory from within the same kernel security authority to achieve local privilege escalation; it does not inherently cross VM, IOMMU, or container sandbox boundaries as a distinct scope change.\\nC:H - The overflow lets BPF code obtain a pointer outside the allocated HID-BPF context buffer and read adjacent kernel heap memory, enabling arbitrary kernel information disclosure and supporting further exploitation primitives.\\nI:H - The same out-of-bounds pointer allows arbitrary kernel heap writes through the returned buffer, enabling control of adjacent objects and potential arbitrary code execution in kernel context.\\nA:H - Large out-of-bounds reads/writes against kmalloc-backed HID-BPF buffers can corrupt critical kernel structures and cause kernel oops, panic, or hang during HID-BPF callback execution.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"658ee5a64fcfbbf758447fa3af425729eaabb0dc\", \"lessThan\": \"f72176bde0cc0e709e41ab170c71e8f229232af6\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"658ee5a64fcfbbf758447fa3af425729eaabb0dc\", \"lessThan\": \"ca373549140dfb386aa2de38364b58441b1f4885\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"658ee5a64fcfbbf758447fa3af425729eaabb0dc\", \"lessThan\": \"61a959b82f1aecd6d2d35c208013dd077cac9d10\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"658ee5a64fcfbbf758447fa3af425729eaabb0dc\", \"lessThan\": \"f81bc5a709dcbaf2a3bbef4ca7167f93900cc39f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"658ee5a64fcfbbf758447fa3af425729eaabb0dc\", \"lessThan\": \"2d044049421dd48212b28646a850749d4a2d57fa\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/hid/bpf/hid_bpf_dispatch.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\": \"6.6.160\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.97\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.40\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/hid/bpf/hid_bpf_dispatch.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/f72176bde0cc0e709e41ab170c71e8f229232af6\"}, {\"url\": \"https://git.kernel.org/stable/c/ca373549140dfb386aa2de38364b58441b1f4885\"}, {\"url\": \"https://git.kernel.org/stable/c/61a959b82f1aecd6d2d35c208013dd077cac9d10\"}, {\"url\": \"https://git.kernel.org/stable/c/f81bc5a709dcbaf2a3bbef4ca7167f93900cc39f\"}, {\"url\": \"https://git.kernel.org/stable/c/2d044049421dd48212b28646a850749d4a2d57fa\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nHID: bpf: Fix hid_bpf_get_data() range check\\n\\nhid_bpf_get_data() returns a pointer into the HID-BPF context data when\\nthe caller-provided offset and size fit inside ctx-\u003eallocated_size.\\n\\nThe current check adds rdwr_buf_size and offset before comparing the\\nresult against ctx-\u003eallocated_size.
