CVE-2022-49581

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2022-49581
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: be2net: Se ha corregido el desbordamiento del búfer en be_get_module_eeprom be_cmd_read_port_transceiver_data asume que se le proporciona un búfer que tiene al menos una longitud de PAGE_DATA_LEN, o el doble si el módulo admite SFF 8472. Sin embargo, este no siempre es el caso. Corrija esto pasando el desplazamiento y la longitud deseados a be_cmd_read_port_transceiver_data para que solo copiemos los bytes una vez.
