Subject: CVE request - kernel: bridge br_multicast NULL pointer dereference

"Somewhere along the line the NULL check in br_mdb_ip_get went AWOL, 
causing crashes when we receive an IGMP packet with no multicast table 
allocated.

This patch restores it and ensures all br_mdb_*_get functions use it."

Did a quick check: net/bridge/br_multicast.c was introduced in eb1d1641 
(2.6.34-rc1), the check was removed in 8ef2a9a5 (v2.6.35-rc1), and 
subsequently restored in 7f285fa78d (v2.6.35-rc5).

Thanks, Eugene
