CVE-2011-0709
The br_mdb_ip_get function in net/bridge/br_multicast.c in the Linux kernel before 2.6.35-rc5 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an IGMP packet, related to lack of a multicast table.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
