A malicious HID descriptor can advertise a large\nfeature field size while an IIO caller supplies a small stack buffer,\nsuch as a single s32, causing an out-of-bounds write.\n\nHID core stores parsed report values in __s32 slots and clamps extracted\nvalues to 32 bits. Reject feature fields that require more than one slot\nper value, guard the total byte count calculation, and clamp each\nper-value copy to the remaining caller buffer."}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"},"scenarios":[{"lang":"en","value":"AV:A - hid-sensor-hub matches HID_BUS_ANY/HID_GROUP_SENSOR_HUB, so a Bluetooth HID/HoGP peripheral can present a Sensor-page descriptor and drive the bug over an adjacent wireless link; USB is only physical, and Adjacent is the most severe reasonable transport.\nAC:L - The attacker fully controls the report descriptor (report_size up to 256 bits, report_count, power-state feature) and GET_REPORT payload; IIO probe then copies report_size/8 bytes into a 4-byte stack buffer with no race or uncontrolled condition required.\nPR:N - A malicious HID peripheral is sufficient: hid-sensor-hub and IIO clients autoload and call sensor_hub_get_feature() during enumeration, with no local account, capability, or init-namespace privilege on the victim.\nUI:N - hid_sensor_parse_common_attributes() calls sensor_hub_get_feature() from IIO probe as soon as the device connects or auto-reconnects and MFD cells are registered; no extra victim open, mount, or confirmation is required.\nS:U - The out-of-bounds write corrupts host kernel stack/heap in HID/IIO processing and does not cross a VM, IOMMU, or other separate security authority.\nC:H - The unbounded memcpy reads field->value and adjacent kernel memory into an overflowed stack frame, and GET_REPORT values are attacker-controlled; this kernel memory corruption can be leveraged for information disclosure.\nI:H - This is a kernel stack out-of-bounds write of up to 32 attacker-influenced bytes into IIO callers' 4-byte s32 buffers, enabling control-flow hijacking; out-of-bounds writes are High integrity.\nA:H - Stack or adjacent-memory corruption from the unbounded copy causes a kernel oops/panic (canary, bad control flow, or heap corruption), denying availability until reboot."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/hid/hid-sensor-hub.c"],"versions":[{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"1c0463f0f028801a933f090cd2695f132635b374","status":"affected","versionType":"git"},{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"4145aa149a32e4b35d5d47e380d0c6c438b4e6fe","status":"affected","versionType":"git"},{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"8bf8aaf2f74de64f801eb30bc38927dba1f8e40a","status":"affected","versionType":"git"},{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"c5c60260a07e627084e792ea959ab468ccfa4d50","status":"affected","versionType":"git"},{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"fa95b14198b6c8ea721b4784f466d3c2c2bac83a","status":"affected","versionType":"git"},{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"9f43499ce6458a572b781f6bb46c464ab59fa825","status":"affected","versionType":"git"},{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"bc3d72c44bff17688dc5f3e5132a53b51dae0f04","status":"affected","versionType":"git"},{"version":"5459ada2b3cd69e6bf1b0c034feb810975d0072b","lessThan":"c92693f3ed099401d0383ef35ca1fe1e6ba033de","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/hid-sensor-hub.c"],"versions":[{"version":"4.9","status":"affected"},{"version":"0","lessThan":"4.9","status":"unaffected","versionType":"semver"},{"version":"5.10.270","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.221","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.109","lessThanOrEqual":"6.12.*","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-rc1","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":"4.9","versionEndExcluding":"5.10.270"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"5.15.221"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.12.109"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"6.18.50"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"7.2.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/1c0463f0f028801a933f090cd2695f132635b374"},{"url":"https://git.kernel.org/stable/c/4145aa149a32e4b35d5d47e380d0c6c438b4e6fe"},{"url":"https://git.kernel.org/stable/c/8bf8aaf2f74de64f801eb30bc38927dba1f8e40a"},{"url":"https://git.kernel.org/stable/c/c5c60260a07e627084e792ea959ab468ccfa4d50"},{"url":"https://git.kernel.org/stable/c/fa95b14198b6c8ea721b4784f466d3c2c2bac83a"},{"url":"https://git.kernel.org/stable/c/9f43499ce6458a572b781f6bb46c464ab59fa825"},{"url":"https://git.kernel.org/stable/c/bc3d72c44bff17688dc5f3e5132a53b51dae0f04"},{"url":"https://git.kernel.org/stable/c/c92693f3ed099401d0383ef35ca1fe1e6ba033de"}],"title":"HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature","x_generator":{"engine":"bippy-1.2.0"}}}}
