CVE-2022-49581

Severity CVSS v4.0:
Pending analysis
Type:
CWE-787 Out-of-bounds Write
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> be2net: Fix buffer overflow in be_get_module_eeprom<br /> <br /> be_cmd_read_port_transceiver_data assumes that it is given a buffer that<br /> is at least PAGE_DATA_LEN long, or twice that if the module supports SFF<br /> 8472. However, this is not always the case.<br /> <br /> Fix this by passing the desired offset and length to<br /> be_cmd_read_port_transceiver_data so that we only copy the bytes once.
