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.\n\n## Affected\n\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < 1c0463f0f028801a933f090cd2695f132635b374`\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < 4145aa149a32e4b35d5d47e380d0c6c438b4e6fe`\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < 8bf8aaf2f74de64f801eb30bc38927dba1f8e40a`\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < c5c60260a07e627084e792ea959ab468ccfa4d50`\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < fa95b14198b6c8ea721b4784f466d3c2c2bac83a`\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < 9f43499ce6458a572b781f6bb46c464ab59fa825`\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < bc3d72c44bff17688dc5f3e5132a53b51dae0f04`\n- `Linux >= 5459ada2b3cd69e6bf1b0c034feb810975d0072b < c92693f3ed099401d0383ef35ca1fe1e6ba033de`\n- `Linux 4.9`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat OpenShift Container Platform 4 · updated 2026-09-16 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89729.json)","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":224592,"id":"CVE-2026-89729","ts":1792401425178,"field":"cvss","old":"7","new":"8.8"},{"seq":205445,"id":"CVE-2026-89729","ts":1789576717845,"field":"cvss","old":"8.8","new":"7"},{"seq":197691,"id":"CVE-2026-89729","ts":1789384318426,"field":"cvss","old":"6.3","new":"8.8"},{"seq":197690,"id":"CVE-2026-89729","ts":1789384318426,"field":"severity","old":"medium","new":"high"},{"seq":183841,"id":"CVE-2026-89729","ts":1789356677630,"field":"cvss","old":"8.8","new":"6.3"},{"seq":183840,"id":"CVE-2026-89729","ts":1789356677630,"field":"severity","old":"high","new":"medium"},{"seq":153614,"id":"CVE-2026-89729","ts":1789285351509,"field":"cvss","old":null,"new":"8.8"},{"seq":153613,"id":"CVE-2026-89729","ts":1789285351509,"field":"severity","old":"none","new":"high"},{"seq":147349,"id":"CVE-2026-89729","ts":1789270210558,"field":"cvss","old":null,"new":"6.3"},{"seq":147348,"id":"CVE-2026-89729","ts":1789270210558,"field":"severity","old":"none","new":"medium"},{"seq":109106,"id":"CVE-2026-89729","ts":1789183730327,"field":"cvss","old":null,"new":"6.3"},{"seq":109105,"id":"CVE-2026-89729","ts":1789183730327,"field":"severity","old":"none","new":"medium"}]}
