Threats tagged 'ghsa-9pw8-8xmv-73cr'

A vulnerability in the Linux kernel's IP multicast routing (ipmr) subsystem allowed a network administrator in a user+net namespace to create many multicast routing tables without proper memory accounting. This caused unreclaimable slab memory growth on the host. The issue was resolved by charging mr_table allocations to memory control groups (memcg) and marking multicast forwarding cache (MFC) caches for accounting. Unresolved MFC entries remain uncharged but are bounded and expire after 10 seconds.
