In the Linux kernel, the following vulnerability has been resolved: HID: multitouch: fix slab out-of-bounds access in mt_report_fixup() A malicious HID device can trigger a slab out-of-bounds during mt_report_fixup() by passing in report descriptor smaller than 607 bytes. mt_report_fixup() attempts to patch byte offset 607 of the descriptor with 0x25 by first checking if byte offset 607 is 0x15 however it lacks bounds checks to verify if the descriptor is big enough before conducting this check. Fix this bug by ensuring the descriptor size is at least 608 bytes before accessing it. Below is...

OS를 선택하면 해당 OS의 제품·패키지·KB·APAR 확인 명령만 표시됩니다.
조치방안
제3자 참조와 수정 버전 값(5.15.191, 6.1.150, 6.6.104, 6.11, 6.12.45, 6.16.5)은 보조 근거로만 사용하고, 공급사 공식 보안 권고에서 조치 기준을 재확인합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, SIMATIC CN 4100, linux kernel 5.15.191, 6.1.150, 6.6.104, 6.11, 6.12.45, 6.16.5 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
