AI-suggested
A fix has been implemented in the Linux kernel to free the EEPROM data during device removal. Users should update to the kernel version that includes this fix. Since this is a kernel-level fix, applying the official kernel update or patch from the Linux distribution vendor will remediate the issue.
Description
A memory leak vulnerability in the Linux kernel's iwlegacy driver for Intel 3945 wireless devices was resolved. The issue occurs because EEPROM data allocated during device probe is not freed upon device removal, leading to a memory leak. This was identified through manual code inspection and fixed by freeing the EEPROM data in the device removal function.
