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.

kernel: Linux kernel: be2net buffer overflow in be_get_module_eeprom
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.
A flaw was found in the Linux kernel's be2net driver. This vulnerability allows a buffer overflow via incorrect buffer length handling in be_cmd_read_port_transceiver_data.
