Intel QuickSPI is a PCI HID-over-SPI touch host, not a network or Bluetooth path.\nAC:L - Opening hidraw and issuing GET_REPORT with a 2-byte ioctl size is enough: hidraw_get_report() kmallocs that size and quickspi_get_report() copies the full device response. A normal touch GET_FEATURE or GET_INPUT_REPORT exceeds 2 bytes, so the overflow does not depend on a race or attacker-uncontrolled layout.\nPR:L - hidraw_open() has no capability check; access is only the hidraw node. Default 0600 is commonly relaxed by udev uaccess or seat ACLs for the logged-in user on laptops and kiosks, so an unprivileged local user can trigger it without init-namespace root.\nUI:N - The attacker opens the hidraw node and issues the ioctl themselves. No separate victim action such as mounting a filesystem or plugging in a device is required at exploit time.\nS:U - The overflow corrupts kernel heap in the HID QuickSPI GET_REPORT path on the same host. That is a standard kernel privilege-escalation impact, not a VM, IOMMU, or other security-authority crossing.\nC:H - quickspi_get_report() memcpy()s qsdev->report_len bytes into an undersized hidraw kmalloc buffer, overflowing adjacent slab objects. That heap corruption can be turned into an arbitrary kernel read, so confidentiality impact is high even though the copied bytes originate from the touch controller.\nI:H - This is an unbounded out-of-bounds kernel heap write. The attacker chooses the destination size, and HID feature reports can be SET then GET so overflow contents are attacker-influenced. Adjacent slab corruption can yield an arbitrary write or control-flow hijack.\nA:H - Overflowing a 2-byte kmalloc object with a typical HID report corrupts neighboring heap metadata and pointers, which reliably causes a kernel oops or panic even if the attacker does not pursue code execution."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/hid/intel-thc-hid/intel-quickspi/quickspi-hid.c", "drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.c", "drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.h"], "versions": [{"version": "4138f21115aec3ebae7805ec3407c72d93558023", "lessThan": "72706b44b665679d7d60a488d8776a911f1a93f3", "status": "affected", "versionType": "git"}, {"version": "4138f21115aec3ebae7805ec3407c72d93558023", "lessThan": "54e0bafc0653bdf2a6c5f5f8ad8787a820d98663", "status": "affected", "versionType": "git"}, {"version": "4138f21115aec3ebae7805ec3407c72d93558023", "lessThan": "035ec4a71cb8020a927c123bbe75c2f88d614986", "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/intel-thc-hid/intel-quickspi/quickspi-hid.c", "drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.c", "drivers/hid/intel-thc-hid/intel-quickspi/quickspi-protocol.h"], "versions": [{"version": "6.14", "status": "affected"}, {"version": "0", "lessThan": "6.14", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.50", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.4", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.3", "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": "6.14", "versionEndExcluding": "6.18.50"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.14", "versionEndExcluding": "7.2.4"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.14", "versionEndExcluding": "7.3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/72706b44b665679d7d60a488d8776a911f1a93f3"}, {"url": "https://git.kernel.org/stable/c/54e0bafc0653bdf2a6c5f5f8ad8787a820d98663"}, {"url": "https://git.kernel.org/stable/c/035ec4a71cb8020a927c123bbe75c2f88d614986"}], "title": "HID: intel-thc-hid: intel-quickspi: bound GET_REPORT response to the caller buffer", "x_generator": {"engine": "bippy-1.2.0"}}}}
