"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nipv6: fib6: fix NULL deref in fib6_walk_continue() on multi-batch dump\n\ninet6_dump_fib() saves its progress in cb->args[1] as a positional\nindex within the current hash chain. Between batches, a concurrent\nfib6_new_table() can insert a new table at the chain head, shifting\nall existing entries. The saved index then lands on a different\ntable, causing fib6_dump_table() to set w->root to the wrong table\nwhile w->node still points into the previous one.\nfib6_walk_continue() dereferences w->node->parent (NULL) and panics:\n\n BUG: kernel NULL pointer dereference, address: 0000000000000008\n RIP: 0010:fib6_walk_continue+0x6e/0x170\n Call Trace:\n <TASK>\n fib6_dump_table.isra.0+0xc5/0x240\n inet6_dump_fib+0xf6/0x420\n rtnl_dumpit+0x30/0xa0\n netlink_dump+0x15b/0x460\n netlink_recvmsg+0x1d6/0x2a0\n ____sys_recvmsg+0x17a/0x190\n\nFix by storing tb->tb6_id in cb->args[1] instead of a positional\nindex. On resume, skip entries until the id matches; a concurrent\nhead-insert can never match the saved id, so the walker always\nresumes on the correct table."
