Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: firmware_loader: Block path traversal
Most firmware names are hardcoded strings, or are constructed from fairly constrained format strings where
the dynamic parts are just some hex numbers or such. However, there are a couple codepaths in the kernel
where firmware file names contain string components that are passed through from a device or semi-
privileged userspace; the ones I could find (not counting interfaces that require root privileges) are: -
lpfc_sli4_request_firmware_update() seems to construct the firmware filename from "ModelName", a string
that was previously parsed out of some descriptor ("Vital Product Data") in lpfc_fill_vpd() -
nfp_net_fw_find() seems to construct a firmware filename from a model name coming from
nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I think parses some descriptor that was read from the
device. (But this case likely isn't exploitable because the format string looks like "netronome/nic_%s",
and there shouldn't be any *folders* starting with "netronome/nic_". The previous case was different
because there, the "%s" is *at the start* of the format string.) - module_flash_fw_schedule() is reachable
from the ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as GENL_UNS_ADMIN_PERM (meaning
CAP_NET_ADMIN inside a user namespace is enough to pass the privilege check), and takes a userspace-
provided firmware name. (But I think to reach this case, you need to have CAP_NET_ADMIN over a network
namespace that a special kind of ethernet device is mapped into, so I think this is not a viable attack
path in practice.) Fix it by rejecting any firmware names containing ".." path components. For what it's
worth, I went looking and haven't found any USB device drivers that use the firmware loader dangerously.
(CVE-2024-47742)
