--- cve: "CVE-2026-89626" severity: "HIGH" cvss: 8.8 epss: "18.8%" vendor: "Linux" kev: false exploited: false published: "2026-09-11 20:19:48" tags: [cve, security, high] source: tsecurity.de CVE-Dossier exported: "2026-09-15T15:09:52+02:00" --- # CVE-2026-89626 > 8.8 HIGH ## Beschreibung In the Linux kernel, the following vulnerability has been resolved: HID: sensor: custom: Fix field sysfs group cleanup on failure hid_sensor_custom_add_attributes() creates one sysfs group for each custom sensor field. If sysfs_create_group() fails after some groups have already been created, the function returns the error without removing the previously created groups. Add a local unwind path to remove the groups that were already created. With enable_sensor exposed only after the field attributes are ready, this path can free sensor_inst->fields without leaving enable_sensor able to access pointers into that array. ## CVSS-Vektor ``` CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Benachbart | warn | | AC Komplexität | Gering | bad | | PR Privilegien | Keine | bad | | UI Interaktion | Keine | bad | | S Scope | Unverändert | good | | C Vertraulichkeit | Hoch | bad | | I Integrität | Hoch | bad | | A Verfügbarkeit | Hoch | bad | ## Patch verfügbar (OSV) - Kernel ≥ 6.12.109 - Kernel ≥ 6.18.50 - Kernel ≥ 7.2.4 ## Referenzen - - - - - - - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/cve?cve=CVE-2026-89626) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI BITS_
