Question on the #CopyFail Linux vulnerability:
If "lsmod | grep algif_aead" returns nothing, is the vulnerability not exploitable?
Most of my Linux machines are running older, non-patched kernels, but it doesn't seem like the affected kernel module is active... so does that mean a system that returns nothing for "lsmod | grep algif_aead" is not at risk for this exploit?
