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.
