be2net: Fix buffer overflow in be_get_module_eeprom

State: Published
Severity: 7.8 High

Description

In the Linux kernel, the following vulnerability has been resolved:

be2net: Fix buffer overflow in be_get_module_eeprom

be_cmd_read_port_transceiver_data assumes that it is given a buffer that is at least PAGE_DATA_LEN long, or twice that if the module supports SFF 8472. However, this is not always the case.

Fix this by passing the desired offset and length to be_cmd_read_port_transceiver_data so that we only copy the bytes once.
