CVE-2022-49904

The CVE-2022-49904 entry documents a Linux kernel vulnerability in net/neigh: a null-ptr-deref in neigh_table_clear() that occurs when IPv6 initialization fails and cleanup calls pneigh_queue_purge() with a NULL device. The fix, as described, is to pass NULL to pneigh_queue_purge() in neigh_ifdow...

CVE-2022-49903

CVE-2022-49903 affects the Linux kernel IPv6 routing: during ip6_route_net_init_late(), if the files ipv6_route or rt6_stats fail to be created, initialization may complete and later removing the proc entries could trigger a WARNING about the missing rt6_stats. The issue is a local-privilege-cont...
