The previous case was different because there,\n the \"%s\" is *at the start* of the format string.)\n - module_flash_fw_schedule() is reachable from the\n ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as\n GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is\n enough to pass the privilege check), and takes a userspace-provided\n firmware name.\n (But I think to reach this case, you need to have CAP_NET_ADMIN over a\n network namespace that a special kind of ethernet device is mapped into,\n so I think this is not a viable attack path in practice.)\n\nFix it by rejecting any firmware names containing \"..\" path components.\n\nFor what it's worth, I went looking and haven't found any USB device\ndrivers that use the firmware loader dangerously."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles":
