Last modified

CVE-2011-1080 is a vulnerability of currently unknown severity. The do_replace function in net/bridge/netfilter/ebtables.c in the Linux kernel before 2.6.39 does not ensure that a certain name field ends with a '\0' character, which allows local users to obtain potentially sensitive information from kernel stack memory by leveraging the CAP_NET_ADMIN capability to replace a table, and then reading a modprobe command line.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
