CVE-2020-14304 [MEDIUM] CVE-2020-14304 kernel: ethtool when reading eeprom of device could lead to memory leak
CVE-2020-14304 kernel: ethtool when reading eeprom of device could lead to memory leak
If running ethtool for reading eeprom of device (param -m or param -e), it can lead to reading some uninitialized values from kernel memory.
However, attacker can just read some unknown values from drivers memory, but cannot control what and where reads and these values related to the driver only. Attacker cannot affect availability and cannot make any other higher impact than such reading.
The rate of issue is low both because need root access for running "ethtool -m/-e" and because it can work only for some specific network drivers.
