In the Linux kernel, the following vulnerability has been resolved: media: mtk-jpeg: Fix use after free bug due to error path handling in mtk_jpeg_dec_device_run In mtk_jpeg_probe, &jpeg->job_timeout_work is bound with mtk_jpeg_job_timeout_work. In mtk_jpeg_dec_device_run, if error happens in mtk_jpeg_set_dec_dst, it will finally start the worker while mark the job as finished by invoking v4l2_m2m_job_finish. There are two methods to trigger the bug. If we remove the module, it which will call mtk_jpeg_remove to make cleanup. The possible sequence is as follows, which will cause a use-after...

OS를 선택하면 해당 OS의 제품·패키지·KB·APAR 확인 명령만 표시됩니다.
조치방안
구조화된 수정 버전 값(5.10.210, 5.15.149, 6.1.76, 6.6.15, 6.7.3)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 5.10.210, 5.15.149, 6.1.76, 6.6.15, 6.7.3 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
