In the Linux kernel, the following vulnerability has been resolved: HID: multitouch: Correct devm device reference for hidinput input_dev name Reference the HID device rather than the input device for the devm allocation of the input_dev name. Referencing the input_dev would lead to a use-after-free when the input_dev was unregistered and subsequently fires a uevent that depends on the name. At the point of firing the uevent, the name would be freed by devres management. Use devm_kasprintf to simplify the logic for allocating memory and formatting the input_dev name string.

조치방안
구조화된 수정 버전 값(4.14.326, 4.19.295, 5.4.257, 5.10.195, 5.15.132, 6.1.53, 6.4.16, 6.5.3)은 참고용입니다. 공급사 공식 보안 권고에서 제품·에디션·설치 방식별 수정 기준을 확인한 뒤 적용합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, linux kernel 4.14.326, 4.19.295, 5.4.257, 5.10.195, 5.15.132, 6.1.53, 6.4.16, 6.5.3 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
