Description
A double free vulnerability was identified and fixed in the Linux kernel's ice driver, specifically in the ice_sf_eth_activate() error path. The flaw occurs when auxiliary_device_add() fails, leading to a double free of the sf_dev structure due to improper error handling. This vulnerability has been addressed in patched versions of the Linux kernel.
