wan/sdla.c in Linux kernel 2.6.x before 2.6.11 and 2.4.x before 2.4.29 does
not require the CAP_SYS_RAWIO privilege for an SDLA firmware upgrade, with
unknown impact and local attack vectors. NOTE: further investigation
suggests that this issue requires root privileges to exploit, since it is
protected by CAP_NET_ADMIN; thus it might not be a vulnerability, although
capabilities provide finer distinctions between privilege levels.
