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: i2c-hid: fix potential buffer overflow in i2c_hid_get_report() `i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data into `ihid->rawbuf`. The former can come from the userspace in the hidraw driver and is only bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set `max_buffer_size` field of `struct hid_ll_driver` which we do not). The latter has size determined at runtime by the maximum size of different report types you could receive on any particular device and can be a much smaller value. Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`. The impact is low since access to hidraw devices requires root.

No security boundary crossing (like VM escape) occurs.\\nC:H - This is a heap buffer overflow of up to ~16KB past the allocated buffer. Heap corruption of this magnitude can be leveraged to read adjacent kernel heap objects, potentially disclosing sensitive kernel memory.\\nI:H - The out-of-bounds write corrupts adjacent kernel heap objects. While the overflow content comes from the I2C device rather than being directly attacker-controlled, a 16KB heap overflow can corrupt critical kernel data structures, potentially enabling code execution through heap grooming techniques.\\nA:H - A heap buffer overflow of up to ~16KB will corrupt adjacent kernel heap objects, reliably causing kernel crashes (oops/panic) from corrupted metadata or invalid pointer dereferences.\"}]}], \"affected\": [{\"product\": \"Linux\", \"vendor\": \"Linux\", \"defaultStatus\": \"unaffected\", \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"programFiles\": [\"drivers/hid/i2c-hid/i2c-hid-core.c\"], \"versions\": [{\"version\": \"85df713377ddc0482071c3e6b64c37bd1e48f1f1\", \"lessThan\": \"f9c9ad89d845f88a1509e9d672f65d234425fde9\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"85df713377ddc0482071c3e6b64c37bd1e48f1f1\", \"lessThan\": \"cff3f619fd1cb40cdd89971df9001f075613d219\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"85df713377ddc0482071c3e6b64c37bd1e48f1f1\", \"lessThan\": \"786ec171788bdf9dda38789163f1b1fbb47f2d1e\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"85df713377ddc0482071c3e6b64c37bd1e48f1f1\", \"lessThan\": \"2124279f1f8c32c1646ce98e75a1a39b23b7db76\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"85df713377ddc0482071c3e6b64c37bd1e48f1f1\", \"lessThan\": \"2497ff38c530b1af0df5130ca9f5ab22c5e92f29\", \"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/hid/i2c-hid/i2c-hid-core.c\"], \"versions\": [{\"version\": \"5.18\", \"status\": \"affected\"}, {\"version\": \"0\", \"lessThan\": \"5.18\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"6.1.163\", \"lessThanOrEqual\": \"6.1.*\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"6.6.124\", \"lessThanOrEqual\": \"6.6.*\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"6.12.70\", \"lessThanOrEqual\": \"6.12.*\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"6.18.10\", \"lessThanOrEqual\": \"6.18.*\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"6.19\", \"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\": \"5.18\", \"versionEndExcluding\": \"6.1.163\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"5.18\", \"versionEndExcluding\": \"6.6.124\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"5.18\", \"versionEndExcluding\": \"6.12.70\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"5.18\", \"versionEndExcluding\": \"6.18.10\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"5.18\", \"versionEndExcluding\": \"6.19\"}]}]}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/f9c9ad89d845f88a1509e9d672f65d234425fde9\"}, {\"url\": \"https://git.kernel.org/stable/c/cff3f619fd1cb40cdd89971df9001f075613d219\"}, {\"url\": \"https://git.kernel.org/stable/c/786ec171788bdf9dda38789163f1b1fbb47f2d1e\"}, {\"url\": \"https://git.kernel.org/stable/c/2124279f1f8c32c1646ce98e75a1a39b23b7db76\"}, {\"url\": \"https://git.kernel.org/stable/c/2497ff38c530b1af0df5130ca9f5ab22c5e92f29\"}], \"title\": \"HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report()\", \"x_generator\": {\"engine\": \"bippy-1.2.0\"}}, \"adp\": [{\"title\": \"CISA ADP Vulnrichment\", \"metrics\": [{\"other\": {\"type\": \"ssvc\", \"content\": {\"id\": \"CVE-2026-23178\", \"role\": \"CISA Coordinator\", \"options\": [{\"Exploitation\": \"none\"}, {\"Automatable\": \"no\"}, {\"Technical Impact\": \"total\"}], \"version\": \"2.0.3\", \"timestamp\": \"2026-10-16T15:06:40.043320Z\"}}}], \"problemTypes\": [{\"descriptions\": [{\"lang\": \"en\", \"type\": \"CWE\", \"cweId\": \"CWE-122\", \"description\": \"CWE-122 Heap-based Buffer Overflow\"}]}], \"providerMetadata\": {\"orgId\": \"134c704f-9b21-4f2e-91b3-4a467353bcc0\", \"shortName\": \"CISA-ADP\", \"dateUpdated\": \"2026-10-16T15:06:40.610Z\"}}]}",
