UnknownEPSS 0.43%

Last modified

CVE-2012-3520 is a vulnerability of currently unknown severity. The Netlink implementation in the Linux kernel before 3.2.30 does not properly handle messages that lack SCM_CREDENTIALS data, which might allow local users to spoof Netlink communication via a crafted message, as demonstrated by a message to (1) Avahi or (2) NetworkManager.. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
