Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ethtool: eeprom: add more safeties to EEPROM Netlink fallback<br />
<br />
The Netlink fallback path for reading module EEPROM<br />
(fallback_set_params()) validates that offset total_len)<br />
return -EINVAL;<br />
<br />
This could lead to surprises in both drivers and device FW.<br />
Add the missing offset + length validation to fallback_set_params(),<br />
mirroring the ioctl.<br />
<br />
Similarly - ethtool core in general, and ethtool_get_any_eeprom()<br />
in particular tries to zero-init all buffers passed to the drivers<br />
to avoid any extra work of zeroing things out. eeprom_fallback()<br />
uses a plain kmalloc(), change it to zalloc.
