A vulnerability in the Linux kernel's IPv6 multicast source filter handling was resolved. The issue involved improper manipulation of RCU-protected linked lists when removing a source filter, causing concurrent readers to access deleted tombstone entries and miss active sources. This could lead to incorrect behavior in IPv6 multicast address checking. The fix involves allocating a new tombstone node and safely retiring the original source filter node.
