Linux Linux, SIMATIC S7-1500 CPU 1518-4 PN/DP MFP, SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP 취약점
In the Linux kernel, the following vulnerability has been resolved: net/mdiobus: Fix potential out-of-bounds read/write access When using publicly available tools like 'mdio-tools' to read/write data from/to network interface and its PHY via mdiobus, there is no verification of parameters passed to the ioctl and it accepts any mdio address. Currently there is support for 32 addresses in kernel via PHY_MAX_ADDR define, but it is possible to pass higher value than that via ioctl. While read/write operation should generally fail in this case, mdiobus provides stats array, where wrong address m...

조치방안
제3자 참조와 수정 버전 값(5.10.239, 5.15.186, 6.1.142, 6.6.94, 6.12.34, 6.15.3)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 S7-1500 CPU 1518-4 PN/DP MFP, SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP 5.10.239, 5.15.186, 6.1.142, 6.6.94, 6.12.34, 6.15.3 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
